[c-nsp] ISP redundancy - internal routing question

[Arturo Servin]

   Yes, it seems ok to use iBGP. You can also run and IGP to get rid of 
the HSRP, because all of them are routers you do not need it. Also an 
IGP will be faster to converge than the HSRP. You can redistribute the 
loopbacks of router A and B trough an IGP and to point your default 
gateways from the L3 switches to the loopbacks of routers A and B.
