please setup your lab similar to previous lab add this line to R2 router eigrp 1  passive-interface Serial0/0  network 10.1.1.0 0.0.0.255  network 172.16.2.0 0.0.0.3  no auto-summary ip route 192.168.0.0 255.255.0.0 172.16.2.1 now R2 have two routes to reach 192.168.1.1 via EIGRP with AD = 90 via static route with AD = 1 R2#sh ip route ... D     192.168.1.0/24 [90 /2323456] via 10.1.1.1, 00:05:57, FastEthernet0/0 S     192.168.0.0/16 [1 /0] via 172.16.2.1 guess.. which path will the router use to reach 192.168.1.1 ? some of you may though that it'll be static because it has AD = 1, let's test.. R2#traceroute 192.168.1.1 ..   1 10.1.1.1 4 msec 4 msec 4 msec   2 172.16.1.1 12 msec 12 msec *   unfortunately it choose to use route learn via EIGRP.. thru R3. This is because it prefer longest prefix match compare to AD destination : 192.168.1.1 EIGRP route = 192.168.1.0/24 Static route = 192.168.0.0/16 EIG...

using static route when dynamic route not available primary link between network 192.168.1.0/24 and 10.1.1.0/24 are thru R3, learn each others via EIGRP . R2 is a backup link in case the primary link is not available *this is not a complete routing solution, this lab only looking from R1 point of view to reach 10.1.1.0/24 R1 interface Loopback1 ip address 192.168.1.1 255.255.255.0 ! interface Serial0/0 ip address 172.16.2.1 255.255.255.252 clock rate 56000 ! interface Serial0/1 ip address 172.16.1.1 255.255.255.252 clock rate 56000 ! router eigrp 1 network 10.0.0.0 network 172.16.1.0 0.0.0.3 network 192.168.1.0 no auto-summary ! ip route 10.1.1.0 255.255.255.0 172.16.2.2 190 !
