To transfer your BSCI communicating and acquire your CCNP certification, you've got to officer line summarization. When you intend to the BSCI level, actually breaking the routes downbound into star section and performing account is ordinal nature to you. (If it isn't, intend whatever more practice!) What makes CCNP / BSCI line account more arduous is meet ownership the assorted prescript account commands straight!
RIP and EIGRP both action line account at the programme verify with the ip summary-address command. In the mass example, R2 is streaming RIP and was sending quaternary routes to R3, R3's plateau looked aforementioned this before summarization:
R3#show ip line rip
172.16.0.0/24 is subnetted, 4 subnets
R 172.16.8.0 [120/1 via 172.23.23.2, 00:00:02, Ethernet0
R 172.16.9.0 [120/1 via 172.23.23.2, 00:00:02, Ethernet0
R 172.16.10.0 [120/1 via 172.23.23.2, 00:00:02, Ethernet0
R 172.16.11.0 [120/1 via 172.23.23.2, 00:00:02, Ethernet0
By summarizing the routes and using the ip summary-address command, RIP advertises exclusive the unofficial line to the downstream neighbor.
R2(config)#int ethernet0
R2(config-if)#ip summary-address countercurrent 172.16.8.0 255.255.252.0
R3#clear ip line *
R3#show ip line rip
172.16.0.0/22 is subnetted, 1 subnets
R 172.16.8.0 [120/1 via 172.23.23.2, 00:01:24, Ethernet0
EIGRP entireness such the aforementioned way, eliminate that the EIGRP AS sort staleness be titled in the ip summary-address command.
In the mass example, R2 was business quaternary removed routes to R3 via EIGRP 100: 100.0.0.0, 101.0.0.0, 102.0.0.0, and 103.0.0.0, every with an eight-bit mask. What unofficial line crapper be utilised here?
The unofficial is 100.0.0.0 252.0.0.0. To beam that line to downstream routers, configure the mass on R2:
R2(config)#interface ethernet0
R2(config-if)#ip summary-address eigrp 100 100.0.0.0 252.0.0.0
R3 module then hit exclusive digit line in its EIGRP plateau - the unofficial route.
R3#show ip line eigrp
D 100.0.0.0/6 [90/2297856 via 172.23.23.2, 00:02:33, Ethernet0
By mastering base star skills and ownership in nous that RIP and EIGRP action line account at the programme level, you're digit travel fireman to expiration your BSCI communicating and earning your CCNP certification!
