I have a 2 ISP/2 local router set up (one ISP on each router). Currently each router is taking a partial routing table, of AS numbers, and then there's a default route.
The 2 local routers are BGP neighbours in the same AS. We run HSRP between our 2 local routers, with the HSRP address acting as the default gateway (primarily on router 1). So most traffic goes to router 1 > Internet, with some going to router 1 > router 2 > Internet (only routes advertised by ISP). Hope that makes sense.
Unfortunately this is causing router 1 to have 3 times as much traffic as router 2, so we would like to try out taking a full routing table on each, and keeping the same HSRP setup.
Router 1 will see any routes advertised by router 2 as AD 200 - is there a way to change the AD to 20 for routes internal to the AS? Otherwise router 1 will prefer its ISP for all routes, and then it will be very unbalanced!
Also, assuming I can manage for both router 1's ISP's and router 2's routes to be considered for router 1's routing table, what order is preference decided on? I guess I would like it to be decided on path first?
I realise that there's helpful documentation out there, particuarly http://www.cisco.com/en/US/tech/tk365/technologies_configuration_example09186a00800945bf.shtml but I don't think it quite covers my scenario.
Any help much appreciated. Is this the completely wrong way to go about this?
