Task 3
R2 should summarize it’s loopback interfaces and advertise a single summary route plus all the specific routes to R1.
The leakmap was introduced in IOS 12.3(14)T and it must be configured under the physical interface and NOT a subinterface.
Configuring leakmap option allows us to advertise a component route (One or more specific networks of a summary route) that would otherwise be suppressed by the manual summarization.
There are three rules to remember:
If the leakmap is configured to reference a routemap that does not exist, only the summary route is advertised and the more specific routes are suppressed.
If the leakmap is configured to reference a routemap and the routemap is referencing an accesslist that does NOT exist, then the summary route plus all the specific routes are advertised.
If the leakmap is configured to reference a routemap and the routemap matches on an accesslist, all the permitted networks by the accesslist will be advertised along with the summary route.
On R2
R2(config)#int F0/0
R2(configif)#ip summaryaddress eigrp 100 2.2.4.0 255.255.252.0 leakmap TEST21 R2(config)#routemap TEST21 permit 10
R2(configroutemap)#match ip addr 99
www.ccieuniversity.com
R2(configroutemap)#exit
Note, the leakmap is referencing a routemap and the routemap is matching on an accesslist that does not exist, therefore, the summary route plus all the specific routes are advertised. If the routemap does not have a match command configured the same will result.
