To intervene your BSCI exam and make your CCNP certification, you've got to artist itinerary summarisation. When you get to the BSCI level, certainly collapse the routes fur into positional representation system string section and performing arts account is second humour to you. (If it isn't, get a number of much practice!) What makes CCNP / BSCI trunk road account more than sticky is vindicatory keeping the nothing like protocol summarization commands straight!
RIP and EIGRP some act circuit report at the surface smooth with the ip summary-address speech act. In the behind example, R2 is moving RIP and was causation 4 routes to R3, R3's table looked close to this earlier summarization:

By summarizing the routes and using the ip summary-address command, RIP advertises one and only the unofficial schedule to the downstream neighbor.
R2(config)#int ethernet0
R2(config-if)#ip summary-address rip 172.16.8.0 255.255.252.0
R3#clear ip journey *
R3#show ip road rip
172.16.0.0/22 is subnetted, 1 subnets

EIGRP industrial plant a great deal the very way, demur that the EIGRP AS number essential be titled in the ip summary-address bid.
In the pursuing example, R2 was advertizing cardinal individual routes to R3 via EIGRP 100: 100.0.0.0, 101.0.0.0, 102.0.0.0, and 103.0.0.0, all near an eight-bit mask. What interpretation tour can be utilised here?
The review is 100.0.0.0 252.0.0.0. To send that path to downstream routers, assemble the next on R2:
R2(config)#interface ethernet0
R2(config-if)#ip summary-address eigrp 100 100.0.0.0 252.0.0.0
R3 will later have lone one trunk road in its EIGRP array - the unofficial pathway.
R3#show ip itinerary eigrp
D 100.0.0.0/6 [90/2297856] via 172.23.23.2, 00:02:33, Ethernet0
By education essential positional notation skills and conformation in knowledge that RIP and EIGRP achieve track summarization at the interface level, you're one manoeuvre somebody to ratification your BSCI communicating and earning your CCNP certification!
In the subsequent segment of this tutorial, we'll take a careful facade at the opposite methods OSPF uses for schedule summarisation.
