DEFAULT-ROUTING

 

 

We have configured 2 cisco routers R1 and R2 with statically assigned default route to reach to the network they don’t know

 

Configuration on cisco router for Default-Routing is as following:

Router(config)#ip route 0.0.0.0 0.0.0.0 (next-hop ip address/exit interface-Id) Administrative Distance 

Default-route has default Administrative Distance value as 1.

So according to topology we have configure R1 and R2 with default route as following:

R1(config)#ip route 0.0.0.0 0.0.0.0 12.0.0.2

Leaving Administrative Distance value as default value

 

To check this route on router command is following:

R1#sh ip route

Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

       E1 - OSPF external type 1, E2 - OSPF external type 2

       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2

       ia - IS-IS inter area, * - candidate default, U - per-user static route

       o - ODR, P - periodic downloaded static route

 

Gateway of last resort is 12.0.0.2 to network 0.0.0.0

 

     12.0.0.0/24 is subnetted, 1 subnets

C       12.0.0.0 is directly connected, FastEthernet0/1

C    192.168.101.0/24 is directly connected, FastEthernet0/0

S*   0.0.0.0/0 [1/0] via 12.0.0.2

 

 

On Router R2 default-route configuration is as following:

R2(config)#ip route 0.0.0.0 0.0.0.0 12.0.0.1

Leaving Administrative distance value as default value

 

To check this route on router command is following:

R2#sh ip route

Codes: C - connected, S - static, R - RIP, M - mobile, B - BGP

       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area

       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2

       E1 - OSPF external type 1, E2 - OSPF external type 2

       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2

       ia - IS-IS inter area, * - candidate default, U - per-user static route

       o - ODR, P - periodic downloaded static route

 

Gateway of last resort is 12.0.0.1 to network 0.0.0.0

 

     12.0.0.0/24 is subnetted, 1 subnets

C       12.0.0.0 is directly connected, FastEthernet0/1

C    192.168.102.0/24 is directly connected, FastEthernet0/0

S*   0.0.0.0/0 [1/0] via 12.0.0.1

ip route 0.0.0.0 0.0.0.0 next hop

Which default route you want to configure?

 

Static default or Dynamicly?

Perform these steps to configure a default route.

  • Enter global configuration mode. device# configure terminal.
  • Enter 0.0. 0.0 0.0. 
  • (Optional) Enable the default network route for static route next-hop resolution
  • (Optional) Configure next-hop recursive lookup to resolve the next-hop gateway
