A lot of sources say configuring MPLS BGP peering using /32 loopbacks is recommended, or even required. So what, if anything, happens when we set up MP-BGP peering using loopbacks with /24 addresses?

Client sites, placed in vrf RED, are running BGP AS65015 with PEs and have the following networks configured: CE1 50.0.0.0/24 50.0.1.0/24...
