Configuring VPN MPLS over ATM with Cisco 3600 Routers and LightStream 1010 Switches

Configuring VPN MPLS over ATM with Cisco 3600 Routers and LightStream 1010 Switches

This howto is based on Cisco Systems similarly titled document, Cisco document ID 10533.

Introduction:

I will cover how to configure VPN MPLS over ATM using the Cisco LS1010 as a provider core and two Cisco 3640's with Ethernet and ATM OC3 as provider edge as well as two Cisco 3620's as customer edge. I am revisiting this exercise originally published by Cisco due to issues with TDP as the default protocol on P1 and LDP on PE1 and PE2.

Prerequisites:

Cisco LS1010 (IOS Image: ls1010-wpk2-mz.121-27b.E3.bin)

Cisco C3640 with NM-1A-OC3MM (IOS Image: c3640-jk9o3s-mz.124-1a.bin)

Conventions:

VPN Terminology:

• CE = Customer Edge Router

• PE = Provider Edge Router

• P = Provider Router

MPLS Terminology:

• LER = Label Edge Router

• LSR = Label Switch Router

• TDP/LDP = Tag Distribution Protocol/Label Distribution Protocol

Configurations:

• PE1 and PE2 are the LERs in our ATM network.

• P1 is the LSR.

• CE1 and CE2 are Customer Edge Routers that unaware of the VPN MPLS process.

• CE1 and CE2 are Ethernet connected to PE1 and PE2 respectively and share RIP over their respective Ethernet Links.

• PE1, PE2 and P1 use OSPF as the IGP with a /32 IP Address on Loopback0 in Area 0, ensure the MTU on the ATM major interface is set to 1500 to avoid dbd errors and adjacency problems. Tag-switching is used on the two OC3 interfaces on the LS1010, MPLS IP is used on the sub-interfaces on PE1 and PE2 as it appears that Tag-switching has been depreciated in IOS 12.4. It is important to note, TDP is the default protocol in IOS 12.1.27b on the LS1010 which was a major problem in our exercise. You will need to change this in global configuration mode in the Cisco LS1010 by typing “mpls label protocol ldp”. LDP assigns labels to the OSPF routes.

• PE1 and PE2 are MP BGP peers.

• RIP routes and MP-BGP routes are cross redistributed on PE1 and PE2.

• PE1 and PE2 maintain separate VRF routing tables.

• The VRF instance on PE1 and PE2 are named “lab-01”

• Our exercise uses the AS form for the RD (Route Distinguisher) example “rd 200:1”.
