[c-nsp] Domain-id configuration in MPLS - Concept

[Vikas Sharma]

Hi,

While configuring domain-id (in MPLS where I have different process ids on
PE), I have redistributed ospf as "redistribute ospf 10 vrf xx". In this
case whn I was looking at the routes (sh ip route) on CE routers loopbak
ip's of CE was in summary net link state (sh ip ospf database) but connected
link (PE-CE) was in type 5 link state. As soon as I changed "redistribute
ospf 10 vrf xx" to "redistribute ospf 10 vrf xx match internal ext 1 ext 2"
both the links are in summary net link state. Can someone explain me this?
All CE routers are in same area "area 0"
