Cannot ping routes even though they are into PE1 table

Aldmar Sousa
Level 1
Level 1

I cannot ping LAN networks behind R1 from PE-1. Even though they are in PE-1 routing table. From R1 I am able to ping LAN networks. SWC I have redistribute EIGRP and BGP. My traceroute from PE-1 towards to LAN network stops on R1. R1 and SWC are running iBGP and R1 with PE-1 are running eBGP.

 

PE-1#sh ip bgp vpnv4 vrf R1
BGP table version is 245, local router ID is 1.1.1.1
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
r RIB-failure, S StaleRoutin

can you share 'show ip route x.x.x.x' hop by hop for the source ip and destination ip in both directions.

also no ACLs?

There are no ACLs
