Hi Everyone,
Have a problem with supernet being advertised from an ASR1006 to our RR's -
Prefix is in the routing table, and in bgp, but the router is only advertising
smaller prefixes to the RR's (/30,/29, 28 etc)...I
dont *think* its due to the PL (As it should be allowing anything less that
/32...which it appears to be doing as /30,/29 etc are being advertised?)
Appreciate any assistance.
** Ah - Update, just noticed as I was about to hit send that the supernet is
not being tagged with any community.....smaller prefixes are though? So
route-map is tagging "some" prefixes within the
supernet?
