  2. Connectivity Description • R 1 and R2 are internet routers with Network_A and Network_B routed respectively by ISP • NAT done on both routers • Public addresses undergo NATing once again in firewall and then packets reach the server farm. • When packets are returning back , their source address is changed in firewall and then those are directed to default gateway. That is R1 and R2 HSRP address of Fa0/0. • Packets those arrived from router 2 must leave from router 2 serial link. So that those will undergo proper NAT. ( in this case a source address ISP B ). • In order to do this a policy based routing is applied on the fa0/0 of R1. This policy routes the packets to fa0/0 of R2 those were arrived from ISP B • In this case can we bundle fa0/0 and fa 0/1 of each router so that redundancy will be achieved. • Can HSRP be formed on such bundled interface , in case R1 fails to work
