Guys,
What does that mean by redistributing PE loopbacks into all
areas.Doesnt loopback/32 flow across ospf areas if we don't use area
range at ABR.Also why do we need /32 loopback address for setting up
LSP?
>From RFC 5328:
IGP route leaking consists of redistributing all specific PE loopback
addresses across area boundaries. As a result, LDP finds in the RIB
an exact match for its FEC and sets up the LSP. As a consequence,
the potential benefits that a multi-area domain may yield are
significantly diminished since a lot of addresses have to be
redistributed by ABRs, and the number of IP entries in the IGP Link
State Database (LSDB), RIB, and Forwarding Information Base (FIB)
maintained by every LSR of the domain (whatever the area/level it
belongs to) cannot be minimized.
