i have a need for a high availability solution for a default gateway configuration. just finished the ccdp and thought it might be interesting to try hsrp on a pair of 2514's. put some of that theory to work. instead of highly resiliant i've managed to configure it for mass failure. arg.., not exactly what i had in mind. now, any time i take down 1 of the 4 links, the connect between 2 remote hosts dies. this is in a lab (production is not a lab, production is not a lab...) so it is a mystery i would like to solve, but it is not critical.
here is the basic config (hope it makes it): pc host 1 -----+----- e0 router 1, e1 ----+--------- pc host 2 | | |----- e0 router 2, e1 ----| the routers act as a default gateway between the internal network (represented by pc host 1) and the external world (represented by pc host 2). i have used 10.3 and 10.4 /16 as the addresses for each side of the divide. i want to run hsrp on both sets of router interfaces so that in the event a router or an interface fails, the traffic impact is minimized. in the real world pc host 2 will be a firewall and there will be other hosts off that segment as well looks easy. sounds plausible. read the cisco docs. looks like it should work. minimal incantations before tickling the keyboard. key in the configs and it fires up nicely. do the show standby thingee and all looks cool. can ping the 2 stations end to end. most excellent. put a router in debug mode. when i pull one of the 4 router cables the router goes through a state change but no bits make it to the far end. not even the shiney ones. bitstream courtesy of ping. maybe i misunderstood what hsrp was suppose to do. the configs are below, along with the show standby results. both are 2514's (2 aui's) and both are running 12.2(1d). probably forgot to put the interface in mumble mode or something equally easy. no laughter, please. thanks in advance. router 1 interface Ethernet0 ip address 10.3.255.2 255.255.0.0 no ip route-cache no ip mroute-cache standby 1 priority 200 preempt standby 1 ip 10.3.0.2 ! interface Ethernet1 ip address 10.4.254.2 255.255.0.0 no ip route-cache no ip mroute-cache standby 2 priority 200 preempt standby 2 ip 10.4.254.10 router 2 interface Ethernet0 ip address 10.3.255.1 255.255.0.0 no ip route-cache no ip mroute-cache standby 1 priority 225 preempt standby 1 ip 10.3.0.2 ! interface Ethernet1 ip address 10.4.254.1 255.255.0.0 no ip route-cache no ip mroute-cache standby 2 priority 150 preempt standby 2 ip 10.4.254.10 results of show standby Router1#show standby Ethernet0 - Group 1 Local state is Standby, priority 200, may preempt Hellotime 3 holdtime 10 Next hello sent in 00:00:00.940 Hot standby IP address is 10.3.0.2 configured Active router is 10.3.255.1 expires in 00:00:09, priority 225 Standby router is local 20 state changes, last state change 00:22:34 Ethernet1 - Group 2 Local state is Active, priority 200, may preempt Hellotime 3 holdtime 10 Next hello sent in 00:00:01.676 Hot standby IP address is 10.4.254.10 configured Active router is local Standby router is 10.4.254.1 expires in 00:00:08 Standby virtual mac address is 0000.0c07.ac02 17 state changes, last state change 00:23:26 Router1# Router2#show standby Ethernet0 - Group 1 Local state is Active, priority 225, may preempt Hellotime 3 holdtime 10 Next hello sent in 00:00:01.010 Hot standby IP address is 10.3.0.2 configured Active router is local Standby router is 10.3.255.2 expires in 00:00:09 Standby virtual mac address is 0000.0c07.ac01 24 state changes, last state change 00:22:04 Ethernet1 - Group 2 Local state is Standby, priority 150, may preempt Hellotime 3 holdtime 10 Next hello sent in 00:00:01.272 Hot standby IP address is 10.4.254.10 configured Active router is 10.4.254.2 expires in 00:00:09, priority 200 Standby router is local 32 state changes, last state change 00:22:25 Router2# Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=64638&t=64638 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
