[c-nsp] ASR1001X additional EBGP peer

[james list]

Dear all
I'd like to have your recommandation.

Our customer runs on ASR1001X an EBGP peering (full routing) with one ISP
and some internal IBGP peering (full routing) with other sites of the
customer.

We'd like to add a new EBGP peering on the same router (with full routing
received from a second carrier) in order to load balance traffic (mainly in
output).
The question is: do you see any issue in terms of
performance/memory/whatelse in adding a new EBGP peering ?
Which is the best way to try to load balance in output ?

>From output following I am not sure if going to upgrade the RAM or not...

Thanks in advance for your help!
Cheers
James
