Hello all gentelman!
Here is my topology.And I am trying to build MPLS VPN. I want to advertise
routes from both CEs to each other across MPLS backbone.
CE1------PE1-----Core1------Core2------PE2------CE2
PE & CE are eBGP neighbor.
Route from CE2 advertise to until PE1. But PE1 seems don't re-advertise
route from CE2 to CE1.
PE1#sh ip bgp vpnv4 all neighbors 172.16.1.2 advertised-routes
BGP table version is 10, local router ID is 1.1.1.3
Status codes: s suppressed, d damped, h history, * valid, > best, i -
internal,
r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete
Network Next Hop Metric LocPrf Weight Path
Route Distinguisher: 64512:1 (default for vrf one)
*>i1.1.1.6/32 1.1.1.4 0 100 0 64513 ?
*>i172.16.2.0/30 1.1.1.4 0 100 0 64513 ?
Total number of prefixes 2
