I was able to get tunnels with secondary addresses to work. Config looked like this :
lo0 172.16.80.1/27 --R1--162.16.1.x/27 --R3--172.16.20.x/28 --R4--172.16.50.x/28 --R5--E0 172.16.100.5/28 lo1 172.16.80.33/27--R1-- .... IGRP/OSPF Redist was at R3. 2 tunnels between R3 and R4 for the 2 .80 subnets on R1 with /28 mask. Tunnel source and dest inside the .80 subnet. Works great; can ping from R5 to both 80.1 and 80.5. IGRP routes appear as they should on R5. Found a good reference on CCO re: split horizon and IGRP/RIP w/ secondary addresses. http://www.cisco.com/warp/public/105/41.html Regards, Gregg Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=29659&t=29659 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
