Hello Experts,
I have a strange issue between 2 routers, R1 and R2, i have ospf running, ipv4 is working good, ipv6 does not, upon checking i see adjacency has not formed between R1 and R2, but not both ways, from R1 i can see Point to point link (1) neighbour, but from R2, there is no neighbour (0), any idea where could be problem, I tried broadcast / nbma, on nbma the link forms but no traffic flow. I dont think its MTU related issues as ipv4 runs well. and the ipv6 i can ping both ways.
They both running 6.36.2.
Many thanks.
