Sorry for late replying. But i think it is the ID adn in the cisco IOS we can use the same PID for IPv4 as well as IPv6 process.

Shivlu,

You currently need to use two different processes if you want to propagate both ipv4 and ipv6 routing information. One is RFC2328 compliant (ospfv2) and the other is RFC2740 compliant.

RFC2328: OSPF Version 2

http://www.ietf.org/rfc/rfc2328.txt?number=2328

RFC2740: OSPF for IPv6:

http://www.ietf.org/rfc/rfc2740.txt?number=2740

Here's a show proc from a router running both ospfv2 and ospfv3.

r1#sh proc | incl OSPF

3 ME D52038 0 15 0 6912/9000 0 OSPF-1 Hello

126 ME 1331F4C 44 338 130 6388/9000 0 OSPFv3-1 Router

133 ME D50CF4 156 339 460 6160/9000 0 OSPF-1 Router

136 ME 1332ED8 4 12 333 7236/9000 0 OSPFv3-1 Hello

As I stated in my previous post, there is some work being done on ospfv3 to support different address families, including ipv4.
