Hi, 

 

I have two directly connected routers:

I did the following pings:

R2>ping  vrf red 10.6.11.130
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.6.11.130, timeout is 2 seconds:

R2>ping  vrf red 2000::10:6:11:8002

What is wrong with the last Ping?

 

Thanks in advance,

Best regards

The address that you are trying to ping is in vrf blue but your ping is trying to access it in vrf red.

That is true, I want to do Inter-VRF-Routing on Router R1. 

 

All 4 Pings are Pings from Router R2 (vrf red) to vrf blue on both Routers. 

 

With IPv4 everything works fine, the IPv6 Ping from

R2 (red) --> R1 (red) --> R1 (blue) --> R2 (blue)

works fine too, the only Problem is the IPv6 Ping from

R2 (red) --> R1 (red) --> R1 (blue)

 

IPv4 works fine for the same ping source/ destination Interface.
