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
