Go CCIE Go!! - A Cisco Certified Internetwork Expert

Pavel,
Wasn’t it you that recently said that the 3rd Edition of the Cert Guide was your primary source of study for the written? If I’ve got that correctly, please check out the second sentence of the second paragraph of page 187. Then go build a simple RIP lab to prove it to yourself.
As a general lab prep strategy, if some person or some book tells you something you don’t agree with, TAKE IT INTO YOUR LAB!! Also, “IOS bug” is an accurate explanation for unexpected behavior less than 10% of the time (my own obviously unscientific estimation).

R5(config-router)#do sh ip route rip R 100.0.0.0/8 [120/2] via 10.0.35.3, 00:00:14, FastEthernet0/1 10.0.0.0/24 is subnetted, 3 subnets R 10.0.13.0 [120/1] via 10.0.35.3, 00:00:14, FastEthernet0/1 13.0.0.0/24 is subnetted, 1 subnets R 13.0.13.0 [120/2] via 10.0.35.3, 00:00:14, FastEthernet0/1
*Mar 1 00:28:02.435: RIP: sending v2 update to 224.0.0.9 via Serial1/1 (10.0.45.5) *Mar 1 00:28:02.439: RIP: build update entries *Mar 1 00:28:02.439: 10.0.13.0/24 via 0.0.0.0, metric 2, tag 0 *Mar 1 00:28:02.443: 10.0.35.0/24 via 0.0.0.0, metric 1, tag 0 *Mar 1 00:28:02.443: 13.0.13.0/24 via 0.0.0.0, metric 3, tag 0 *Mar 1 00:28:02.443: 100.0.0.0/8 via 0.0.0.0, metric 3, tag 0
The formatting of the above probably got all hosed up but try to find the metric for 100.0.00.0/8 as displayed in the routing table and then try to find the advertised metric for that same subnet out S1/1. It’s two and three, respectively. Likewise for the 13.0.13.0/24 network.

1. Whenever RIP sends out updates, it sends them with it’s OWN metric (hop count) and RECEIVING router has to increment it. 2. Just two days ago my colleague told me, that during his lab training RIP was not doing that - it was an IOS bug. So try another IOS version if two routers report the same hop count.
