My topology is working perfectly fine and is as follows:
CE1 <-> PE1 <-> P1 <-> P2 <-> PE2 <-> CE2
CE1 <-> PE1and
CE2 <-> PE2are having OSPFv3 with address-family ipv4 and ipv6 both.
PE1 <-> PE2is running MP-iBGP with dual-stack support
Redistribution of OSPF in MP-iBGP is as follows:
Config snippet in PE1 & PE2:
address-family ipv6 vrf custA redistribute connected redistribute ospf 6 no sync address-family ipv4 vrf custA redistribute connected redistribute ospfv3 6 no sync
CE1 & CE2 are able to reach the IPv4 and IPv6 subnets of each other.
What is the difference in these two highlighted commands:
ipv6 address-family it should be
redistribute ospf 6 command while in
ipv4 address-family it should always be
redistribute ospfv3 6. If I interchange these commands within the address-families, both IPv4 & IPv6 networks of CE1 & CE2 become unreachable.
Seems to be a mystery to me. Pl let me know if any other details are required. Any clarification is appreciated.
