Hey Kim, Perhaps because 192.168.0.64/25 is not a valid subnet? With a /25 your first 2 networks are .0 and .128. To summarize I believe you need at least one of the networks within the summary in you RIB. Try ip summar-address 192.168.0.64 255.255.255.192
------Original Message------ From: Kim Pedersen Sender: [email protected] To: CCIE OSL Subject: [OSL | CCIE_RS] RIP autosummary Vs. manual summary Sent: Aug 25, 2009 9:46 AM Hi All, So i was playing around with RIP (As i usually do when im bored :) ), and i came across an issue where my results dont agree with the Cisco documentation. What im talking about is the manual summary ("ip summary-address rip <network> <mask>"). According to: http://www.cisco.com/en/US/docs/ios/12_1/iproute/command/reference/1rdrip.html#wp1025730 The use of a manual summary address, should override the auto-summary functionality. This does not match up to what im able to lab up: R1 <-> R2 <-> R3. On R2, i have the 192.168.0.64/28 configured. between R2 and R3 is 172.16.0.0, so its a different major net. Rip should with autosummary summarize the 192.168.0.64 subnet to 255.255.255.0... This works perfectly. When i then try on the interface between R2 and R3, and do a "ip summary-address rip 192.168.0.64 255.255.255.128" it should override the autosummary, and send this network as a /25 instead of a /24. Anyone able to elaborate on this? Thanks!
