Also, are you aware that some networks inject the IXP LAN into their IGP for the purposes of TE? (I.e leaving the IXP LAN next hop present in their iBGP and then doing MPLS TE on this LAN as opposed to next-hop-self on the border where all peering networks are collapsed into a single loopback)
Yeah, I did. At some point.
Hi all,
I did too for managing my 2 exits to a single IXP. This had rgeat advantages:
simple and best for convergence with Cisco BGP PIC.
However I had big problems few times when PE redistributed the LAN prefix while
there was no connectivity due to broken switch fabric on Brocade MLX of the
IXP. (Note I was managing also the IXP so no excuse! :-) … So I decided to
change this for next-hop-self :-)
SHOULD works for me then :-)
Cheers,
Jerome
Maybe we need to add a bit more language to the point of "if you
need to deviate from these recommendations, understand why you are
doing this, and then feel free to do so" (= "SHOULD" normative
language).
