Issues I have with secondary ip address's : In the sh ip int br command, the 10.x.x.x secondary on the below interface does not show up....
The dhcp request for that interface will advertise out the primary interface not the secondary address, so it is extremely difficult to get the secondary ip address's a dhcp address.... It adds a lot of overhead to the interface connection tables and hsrp can act strange on certain routers, especially older routers with resource limits... interface FastEthernet1/0 description 590 Brennan St. ip address 10.17.212.2 255.255.255.0 secondary ip address 171.70.34.3 255.255.255.0 no ip redirects arp timeout 1740 standby priority 105 preempt standby ip 171.70.34.1 standby track Se6/0/0 standby 2 priority 105 preempt standby 2 ip 10.17.212.1 standby 2 track Se6/0/0 hold-queue 150 in sjbrn-gw1#sh ip int br Ethernet0/0 192.168.54.131 YES NVRAM up up FastEthernet1/0 171.70.34.3 YES NVRAM up up Serial6/0/0 171.68.2.22 YES NVRAM up up Larry Letterman Network Engineer Cisco Systems ----- Original Message ----- From: "Kelly Cobean" To: "Larry Letterman" ; "Cisco groupstudy" Sent: Wednesday, February 12, 2003 7:01 PM Subject: RE: HSRP question > Larry, > Care to elaborate a little on the downside to doing this?
