L3 VPN and MPLS core

Unanswered Question

Hi all,


1) I am new to MPLS and trying to configure a scenario in a non production environment. Is it possible to have L3 VPN's without using BGP in MPLS core network? For some reason I am more inclined to use RIPv2, EIGRP or OSPF in the core.

2) Is it possible to use 2600 series router as PE?


Thanks in advance.

Shah,


1. BGP is indeed required to propagated advertisements from one PE to another. You can use whatever other protocol you'd like as and IGP though.


2. It is indeed possible to use a 2600 in this context.

you would need 12.3 or later. Please refer to CCO for the RAM/Flash requirements.

hi SHAH

to add to the nice cooments in the discussion

the BGP used with mpls and L3 VPN called MP-BGP


the VPN in with VRFs, RD and RT each one add to the ip packet an identifier to distingush the packet with the provider network from other packet and make it uniqe to pass these identifiers from router to router especiallt from PE router to PE router u need the BGP (MP-BGP)


hope this helpful
