Hey, I know, let's use SSM and flush MSDP.

This should work.

What I would recommend however is setting up anycast RP mesh using internal MSDP, then
any one of the RP mesh can be an eMSDP peer - for example, one at the
border.

Hi,

In ALL interdomain multicast docs you could see that interdomain MSDP
session are always setup between RP's in both domains.
I have also found that it is recommended to do it this way.
It sounds logic if RP is close to the border but why would you setup it this
way if RP is many hops away,
in my opinion a border router or RR which runs eMBGP would run eMSDP just
fine, as long as it has iMSDP session with RP.

Any suggestion would be highly appreciated,

Thanks,
Jeff
