MPLS and OSPF

I’m beginning to learn a bit about MPLS and have just completed some MPLS OSPF setup. I must say, it seems a bit more complicated than it’s worth. Ok, so by default, even links in the same area are advertised as type 3 summary LSAs. I’m going to work on the sham-link which is supposed to alleviate this particular issue.

regardless, here’s a few tidbits for studying: make sure you can originate a default route from one CE router and have it picked up as a type 5 LSA in other areas. There are a few tricks to get this working.

(correction: they’re type 3 summary LSAs. I originally said they were type 2)

One thought on “MPLS and OSPF”

  1. “so by default, even links in the same area are advertised as type 2 summary LSAs”

    They are advertised as type 3 Summary LSA’s ——- I Guess
