Hi,

I have two routers directly connected. I can ping the interfaces IP addres, but can´t ping between loopbacks.

Hi,

can you do debug ipv6 pack det on left device then ping the loop of right device and post the log output.

Regards.

Hi,

ok so the packets are sent out the correct interface and with correct next-hop.

Can you do the same debug on the other end while pinging from here and post output ?

Regards.

Hi,

ok but i would have liked to get the output on R2 when pinging from R1.

Can you do this also? because you were pinging from Lo interface on r1 also when unsuccessful ?

Regards.

Hi,

can you redo a ping from R1 to R2 loopback then from R1 sourcing from Loopback to R2 Loopback while disabling debug for ipv6 packet and enabling debug ipv6 icmp on both sides and post results.

Regards.

Hi,

I fixed an interface vlan with ipv6 address 2803:6000:15::1/48. I had good results from both routers, but I don´t understand, what is the difference?

I also placed the same loopback ip add in the same interface vlan and was working (at the end)

It seems like it doesn´t work with interface loopback, this happens only at 3750me.

Regards
