EIGRP Filtering with AD

We have filtered the R6 loopback on R2, R3 and R4's S0/0.14 but BB2 will be getting the loopback address from R4. Because R4 will be learning the loopback from s0/1 directly connected  interface.

So we want to filter R6 loopback on BB2's ip routing table. This we can achieve filter with AD value.

BB2#sh ip route 150.6.6.0

Routing entry for 150.6.6.0/24

  Known via "eigrp 100", distance 90, metric 2277376, type internal

  Redistributing via eigrp 100

  Last update from 155.1.42.4 on FastEthernet0/0, 00:00:02 ago

  Routing Descriptor Blocks:

  * 155.1.42.4, from 155.1.42.4, 00:00:02 ago, via FastEthernet0/0

      Route metric is 2277376, traffic share count is 1

      Total delay is 24200 microseconds, minimum bandwidth is 1544 Kbit

      Reliability 255/255, minimum MTU 1500 bytes

      Loading 1/255, Hops 3

To filter with AD. We should create a access-list and add the distance/ AD value.

BB2#sh run | in acces

access-list 1 permit 150.6.6.0 0.0.0.255

BB2#ping 150.6.6.6

Sending 5, 100-byte ICMP Echos to 150.6.6.6, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 196/308/436 ms

Ping is reachable amazed its not magic its because we having the default route.
