/32 for peering

[netbeginner]

Hi All,

Searching on a query on MPLS ;

First take a look on scnerio ->

PE(Router1) --- Core Rtr -- Core Rtr - PE(Router2)

Is this recommended to form peering between MPLS PE using loopback (/32) only, if really there is any logic ...please share why ?

Consider the case where there are redundant links.

Using the loopback addresses mean the PE's can still talk to each other for the MPLS circuit without being concerned about which link is being used.
