Hello

Please review here BGP ORR

Hello @mautez_mah ,

multiple designs are possible but:

a) peering has to be done on loopbacks

b) thoese loopbacks have do to be advertised in IGP: OSPF or IS-IS or EIGRP.

c) multi level reflection is possibile specially for Global routing table

d) dedidacted per AF  route reflector are possible

e) for MPLS services is possible to partition based on route target filter tag

In my experience the route reflectors are the brains of a service provider and they must be protected to avoid greatest iusses = out of MPLS or multicast or unkwon BUM traffic.

Hope to help

Giuseppe

@Giuseppe Larosa 

could you explain more plz what do you mean for AF 

[Giuseppe Larosa]

Hello @mautez_mah ,

I apologize AF = Address Family

SAFI = Sub Address Family

BGPv4 was created to advertised IPv4 unicast only, with time thanks to its flexible implementation Multi protocol BGP was introduced to advertise other services like;

MPLS L3 VPN

MPLS 6PE

MPLS 6VPE

MPLS VPLS (two subtypes)

NG MVPN

EVPN

...

Hope to help
