Hi all,
I've been working on trying to get LSM working between a couple of A9Ks to
support a SSM based IPTV application.
After ingesting a bunch of content on the subject, I think what I want is
Partitioned MDT, MP2MP with BGP-AD/mLDP (PIM-free core). I'm wondering if
anyone has any links to working configuration examples for this type of MVPN or
some good troubleshooting guides for this type of MVPN specifically.
The XR 4.3 configuration guide seems to provide either a broken or an
incomplete example, so what I've managed to work out from it, doesn't seem to
work.
By 'doesn't seem to work', I mean I have a SSM based join-group configured on a
CE with a PIM adjacency to XR PE1. XR PE1 sees the (S,G) from the CE, but the
adjacent XR PE2 (config below) doesn't see it.
Thanks in advance for any pointers.
