I am managed to set up a BGP/MPLS VPN in a laboratory using CS3620 routers running IOS 12.2(3) with ISIS. I am thinking of using static routes among the PE and P routers instead of a IGP. Does anyone know if Cisco routers supports static configuration of LSP? I have tried but could not get it work.
static routing the the core is supported. Just make sure you have connectivity between all loopback addresses (for BGP and LDP). This might involve quite a number of static routes and a single one missing might break everything.
Can you post your configs (MPLS relevant part)? Maybe we can pinpoint the problem.
Thanks for the reply. I have 4 LSR namely PE1, P1, P2 & PE2 that forms the MPLS core.
Attached is the config for PE1, P2 & PE2
I have no connectivity problem between the LSRs. However, my MPLS forwarding table for each LSR has no tags. Do I have to manually create them, i.e. to bind the tags to the prefixes or do I expect the label distribution is done automatic?
