ATM SVC Howto: ATM SVC between two or more ATM switches

ATM SVC Howto: ATM SVC between two or more ATM switches

You will need to do very little on your ATM switchgear to facilitate an SVC, just verify the switches NSAP address and make a note of it.  For the purpose of this howto we will enable PNNI and use the default configuration on the ATM switch’s ATM Interfaces

The ATM Private Network-Node Interface (PNNI), an ATM network-to-network signaling protocol, provides mechanisms to support scalable, QoS-based ATM routing and switch-to-switch switched virtual connection (SVC) interoperability.

The PNNI (Private Network-to-Network Interface), is a hierarchical, dynamic link-state routing protocol. It is designed to support large-scale ATM networks. The PNNI protocol uses VPI/VCI 0,18 for its messages. In addition, it uses signalling messages to support connection establishment across multiple networks. PNNI is based on UNI 4.0 and Q.2931. Specific information elements were added to UNI 4.0 in order to support the routing process of PNNI. PNNI Signalling contains the procedure to dynamically establish, maintain and clear ATM connections at the private network to network interface or network node interface between 2 ATM networks or 2 ATM network nodes. The PNNI signalling protocol is based on the ATM forum UNI specification and on Q.2931 .

QSAAL and ILMI PVCs

An SVC is dynamically established, maintained and released. It allows you to provide bandwidth on demand for a particular connection or set of user traffic. When configuring SVCs on Cisco router ATM interfaces, you need to configure the following two permanent virtual circuits (PVCs):

·         pvc 0/5 qsaal (Required)—Configures the signaling PVC. SVC service requires a signaling protocol between the end-device and the ATM switch. Cisco IOS® Software conforms to the ATM Forum's UNI 3.0, UNI 3.1 or UNI 4.0 user-to-network signaling standard, depending on what version is selected by Interim Local Management Interface (ILMI) or configuration.

·         pvc 0/16 ilmi (Optional)—Configures an ILMI PVC. The ATM router interface exchanges ILMI packets to communicate ATM-layer addressing information and to register its complete ATM address with the directly attached switch, which then provides ATM-layer routing to the destination router. Refer to Understanding ILMI on ATM Interfaces.

Both of these overhead PVCs are configured on the ATM main interface.

Config Snip 1.1

 no ip mroute-cache

 atm uni-version 3.0

 no atm ilmi-keepalive

 pvc 0/5 qsaal

 pvc 0/16 ilmi

 !

In my example, I’ve created a multipoint subinterface on ATM5/0/0 to allow me to pass BGP traffic between multiple routers on the same subnet.

Config Snip 1.2

interface ATM5/0/0.100 multipoint

 no ip route-cache

 no ip mroute-cache

 map-group isi-backbone

 atm esi-address 100000111111.00

The end system identifier (ESI) address form is preferred in that it automatically handles advertising the address. Use the network service access point (NSAP) form of the command when you need to define a full 20-byte unique address with a prefix unrelated to the network prefix on that interface. You only need to specify a static route when configuring an ARP client using an NSAP address.

To find the NSAP address of the adjacent ATM switch you can use the following at the IOS CLI:

Example 1.3

isi-7507-1#sh atm ilmi-status

Interface : ATM5/0/0 Interface Type : Private UNI (User-side)

ILMI VCC : (0, 16) ILMI Keepalive : Disabled

ILMI State:       UpAndNormal

Peer IP Addr:     172.16.0.235    Peer IF Name:     ATM3/0/1

Peer MaxVPIbits:  8               Peer MaxVCIbits:  14

Active Prefix(s) :

47.0091.8100.0000.0030.f206.bc01

End-System Registered Address(s) :

47.0091.8100.0000.0030.f206.bc01.1000.0011.1111.00(Confirmed)

isi-7507-1#

 

You need to perform the same tasks on the console of the other routers that you would like to add to your ATM network.

 

Lastly, you need to configure an ATM map-list to map IP to the End-System Registered Address for each router in the network.  Notice back at Code Snip 1.2 the map-group “isi-backbone” is configured at the global config level and then applied on the sub-interface ATM5/0/0.100.

mini HowTo on getting a RANCID implementation on it feet

RANCID - Really Awesome New Cisco confIg Differ

 

This is a mini HowTo on getting a RANCID implementation on it feet, for complete documentation please visit  the official website for RANCID found @ http://www.shrubbery.net/rancid/

Download the package at ftp://ftp.shrubbery.net/pub/rancid/rancid-2.3.1.tar.gz

You will want to run this on BSD or some flavor of Linux.

Dependencies:

Expect needs to be installed, try “yum -y install expect”

rancid will also need to have the following packages:

cvs            Code revision system available from prep.ai.mit.edu:/pub/gnu
gnudiff        gnudiff provides the uni-diff (-u) option.  If you do not have
                 a diff that supports -u, configure will set-up rancid to use
                 'diff -c' or 'diff -C'.
perl5           perl version 5 or greater available from www.cpan.org
expect        http://expect.nist.gov/  We highly suggest that you stick to
                 expect 5.24.1 (or so).  This seems to work best.  Note that
                 you need to have the accompanying tcl &/ tk.
svn            Code revision system, an alternative to cvs.  Available from
                 http://subversion.tigris.org/tarballs/.  Use the configure
                 option --enable-svn to configure for Subversion.
tcl             Required by expect.

Lets get started!

Drop the gzipped tarball into /opt and untar it using “tar zxvf rancid-2.3.1.tar.gz”

Cd to the directory where rancid was extracted and read the install and readme files.

Then execute:

[root@mybox rancid-2.3.x]# ./configure --prefix=/usr/local/rancid/

Then type make

Then make install

 

I’m just running this as root – I know, shame on me but I just wanted it up fast!

Edit the file /usr/local/rancid/etc/rancid.conf

(I am using SVN for the repo so I changed "RCSSYS=svn; export RCSSYS")

here is what mine looks like

# rancid 2.3.2a6
# This file sets up the environment used for rancid.  see rancid.conf(5)
#
# This will be site specific
#
TERM=network;export TERM
#

Run the rancid-cvs command to create the /usr/local/var/networking directory and its database and network device list files.

 

Creat the file "/root/.cloginrc"

 Example:

[root@blzsfed60bg ~]# cat .cloginrc
#Routers
add password * consolepass enablepass

Now, there is a file called Router.db located in each group directory, for me that location is:

/usr/local/rancid/var

My groups are:

ISI_ATM_Backbone
ISI_Lab_Firewalls
ISI_Lab_Routers
ISI_Lab_Switchgear
ISI_Prod_Firewalls
ISI_Prod_Routers
ISI_Prod_Switchgear

You can call them whatever you want - that was done in the rancid.conf. 

Below is a sample of one of my Router.db files 

[root@blzsfed60bg ISI_Lab_Routers]# cat router.db
10.10.107.1:cisco:up
10.10.107.2:cisco:up
172.30.100.26:cisco:up
[root@blzsfed60bg ISI_Lab_Routers]# 

 Here is my crontab for the root user, you can see that rancid is schedule to run every hour.

 [root@blzsfed60bg etc]# crontab -l
*/1 * * * * /scripts/cacti_poller.sh > /dev/null 2>&1
1 * * * * /usr/local/rancid/bin/rancid-run > /dev/null 2>&1
50 23 * * * /usr/bin/find /usr/local/rancid/var/logs -type f -mtime +2 -exec rm {} \;
[root@blzsfed60bg etc]#

make sure you start SVN by issuing the command "/usr/bin/svnserve -d"

Download Tortoise SVN client and install it on the computer you will access the repo from.

 To access your REPO - right click on your desktop, you should see the following:

 Click on Repo-browser an you see the following:

 Type in the path to your REPO and click OK, you should see something similar to the following:

(note - I have right clicked on 7.7.7.3 and selected "Log Messages" in the screenshot below) 

 

  Right click on the Modified item and choose "Show didderences" You well see a diff such as the following:

There you have it!

Disclamer - If you want detailed instruction on setting up rancid, you should go to:

Peter Harrison has done a great job of putting this information together and his howto is great.

Also, I have some troubleshooting notes @ forums.routermonkey.org regarding the mail function of Rancid.
