Shouldn't "next-hop-self" be configured on CAT2 and Cat3
This is the only way to get the BGP to show the correct next-hop
see below:
Cat2(config-router)#sib
BGP table version is 7, local router ID is 110.99.102.102
Status codes: s suppressed, d damped, h history, * valid, > best, i - internal,
r RIB-failure, S Stale
Origin codes: i - IGP, e - EGP, ? - incomplete

*> 172.16.4.0/24 110.99.101.101 0 0 3550 i
Without it, and this is what the PG does, all the next hops would says
110.99.101.101 which technically does not meet the requirement!
