OSPF & IPv6

[Gordon Ross]

I'm running a 3750-X with the IP Services feature set and IOS 15.0(2)

I've setup IPv4 routing with OSPF, using the config:

router ospf 1234

  network 1.2.3.0 0.0.0.255 area 0.0.0.0

  ...

I then added IPv6:

ipv6 router ospf 2048

interface vlan500

  ipv6 address ....

  ipv6 ospf 2048 area 0

Only OSPFv3 supports IPv6, so this has created an OSPFv3 process.

I assume the IPv4 OSPF process is still running as a V2 process..?

Do the process IDs have to be different between the v2 & v3 OSPF processes ? What happens if they are the same ? Does IOS treat OSPFv3 purely for IPv6 and OSPFv2 purely for IPv4 ?

Hi,

you can use same PID for both and it will work, IOS will separate the 2 processes(one for v4 and the other for v6).
