Thanks !
On H2. on Merging section. Do we need to go for LOCAL-AS Option towards the RR - R1 ? So we need to delete and create the BGP with new process ID (like we do in H2+)?

you need to add the following in TTL1

permit udp any any

otherwise the any traceroute from the spokes (R19,20,21) to the rest of the network will show the following in the traceroute output

1. * * *

[ASN373]

if the output asks you to have (65001 65001) then use the as-override in the PE routers.

if the output asks you to have (65001 65002) then use the allowas-in in the CE routers.

That is my solution for this variation

i think it is more accurate to add the port range:
ip access-list extended PASS-TTL
permit ospf any any
permit tcp any any eq bgp
permit tcp any eq bgp any
permit pim any any
permit esp any any
permit gre any any
permit udp any any eq 500
permit udp any any eq 4500
perm udp any any ra 33434 33534 <-- for traceroute
