Three methods for EIGRP default routing advertisements and implementation of the rollup

First, eigrp default route

1. Redistribution of static routes

First make sure to make a static default route on the R1, and the second step to distribute the default route to EIGRP

IP Route 0.0.0.0 0.0.0.0 S0/1

Redistribute static

Before redistribution

Gateway of last resort are not set

35.0.0.0/24 is subnetted, 1 subnets

C 35.1.1.0 is directly connected, SERIAL0/1

13.0.0.0/24 is subnetted, 1 subnets

C 13.1.1.0 is directly connected, serial0/0

After redistribution

Gateway of last resort are 13.1.1.1 to network 0.0.0.0

35.0.0.0/24 is subnetted, 1 subnets

C 35.1.1.0 is directly connected, SERIAL0/1

13.0.0.0/24 is subnetted, 1 subnets

C 13.1.1.0 is directly connected, serial0/0

D*ex 0.0.0.0/0 [170/2681856] via 13.1.1.1, 00:00:03, serial0/0

2. Network 0.0.0.0

In R1 to do the default route, the next jump point to the external network port; The second step network 0.0.0.0

Gateway of last resort are 13.1.1.1 to network 0.0.0.0

35.0.0.0/24 is subnetted, 1 subnets

C 35.1.1.0 is directly connected, SERIAL0/1

D 200.1.1.0/24 [90/2297856] via 13.1.1.1, 00:00:02, serial0/0

13.0.0.0/24 is subnetted, 1 subnets

C 13.1.1.0 is directly connected, serial0/0

d* 0.0.0.0/0 [90/2297856] via 13.1.1.1, 00:00:02, serial0/0

3.ip Default-network

Under the global IP default-network 10.0.0.0

Network 10.0.0.0 under Routing process

Local 10.0.0.0/8 routing, with IP route 10.0.0.0 255.0.0.0

Gateway of last resort are not set

35.0.0.0/24 is subnetted, 1 subnets

C 35.1.1.0 is directly connected, SERIAL0/1

10.0.0.0/8 is variably subnetted, 2 subnets, 2 masks

D 10.1.1.0/24 [90/2297856] via 13.1.1.1, 00:00:29, serial0/0

d* 10.0.0.0/8 [90/2169856] via 13.1.1.1, 00:00:01, serial0/0

13.0.0.0/24 is subnetted, 1 subnets

C 13.1.1.0 is directly connected, serial0/0
