[c-nsp] ISP redundancy - internal routing question

[Skeeve Stevens]

Sort of related to the Router/Switch redundancy.

I plan to have two 7200 routers connected multiple upstreams for redundancy.

           {ISP-A}       {ISP-C}
              |             |
              |             |
 {ISP-B}--[RouterA]<--->[RouterB]--{ISP D}  <--Inter-connect between Routers
              |             |  
              M-------------S    
                     |            <--HSRP
                     |
            ------------------- 
           |                   |    
      -----------        ------------ 
     |    L3     |      |     L3     |
     |  switch   |      |   switch   |
     |           |      |            |
      -----------        ------------ 

I have an inter-connect between the routers.

HSRP is running and RouterA is the master.

All traffic will go to RouterA then from there it could go out ISP-A, ISP-B
or over to RouterB then out ISP-C or ISP-D.

The question is. what is the best way for RouterB to announce what routes it
knows about to RouterA.  I am going to assume a iBGP session between each
other, and then give a weighting to what I want to go to RouterB?
