Re: MSDP

I can set ip up both ways and it works cause there is reachability.

So if ebgp peer is set to peer with your interface and yoiu set up your msdp
to peer using loopback addresses, then from what is stated below would mean
that I have done my config incorrectly.

This is why is asked, it is in the DOC CD.

Take from:

ip msdp peer Usage Guidelines

If you are also BGP peering with this MSDP peer, you should use the same IP
address for MSDP as you do for BGP. However, you are not required to run BGP
or MBGP with the MSDP peer, as long as there is a BGP or MBGP path between
the MSDP peers. If there is not, you must configure the *ip msdp
default-peer* command.
 Examples

The following example configures the router at the IP address 131.108.1.2 as
an MSDP peer to the local router. The neighbor belongs to autonomous system
109.

ip msdp peer 131.108.1.2 connect-source ethernet 0

 router bgp 110

  network 131.108.0.0

  neighbor 131.108.1.2 remote-as 109

  neighbor 131.108.1.2 update-source ethernet 0
