Lab 41 - EIGRP Summarization with Default Route

Lab 41 - EIGRP Summarization with Default Route
Di Posting Oleh : Simple Learning
Kategori : Core Technologies EIGRP Routing

Prerequisites: CCNP level skills.

EIGRP (as per CCNP track) offers a plethora of ways to summarize the prefixes:

1. Automatic Summarization.
2. Summarization ('ip summary-address).
3. Summarization with a Default Route.
4. Summarization with a Floating Default Route (floating summary route).
5. Summarization with Administrative Distance 255.
6. Selective Summarization with a Leak Map.

EIGRP is running on all interfaces (pic. 1). Check routing table on R3.

Task 2
Configure summarization so that R3 receives only default route from R1.

Lab Solution

Task 1

EIGRP is running on all interfaces (pic. 1). Check routing table on R3.

Pic. 2 - R3's Routing Table.

Task 2
Configure summarization so that R3 receives only default route from R1.

R1 Configuration:

!

interface Serial0/1
 ip address 10.1.13.1 255.255.255.0
 ip summary-address eigrp 1 0.0.0.0 0.0.0.0 5

!
