Route Summarization is used to reduce routing table and advertise aggregate one
single route.
Disadvantage :- Router will drop traffic when it doesn’t have matching destination in its routing table.
Task 1:- enable eigrp protocol and route summarization and check routing table
In R0 10.0.0.0/8 has been summarized but it doesn’t update in its routing table
and it doesn’t have any route to reach loopback 10.1.0.1 to 10.4.0.1
In R2 if I ping loopback 10.1.0.1 then traffic forward interface 192.168.3.2 and then it will found there is no any ip address in network then the packet will be drop.
Task 2:- disable auto-summary and check and ping
After disable auto-summarization it will update all prefixes and on R3 if I ping
loopback 10.1.0.1 then it will forward via 192.168.3.1
