HSRP with Secondary IP

vinoth.kumar · ‎06-16-2009

Hi,

we are using the two 7206 VXR NPEG2 router as our backbone router and we planned to confiure the HSRP between the router

BGP PRI:

interface GigabitEthernet0/3

description BGP-PRI

ip address 2XX.XX.XX.252 255.255.255.0 secondary

ip address 2X.20.XX.17 255.255.255.0 -- ISP Link A

duplex auto

speed auto

media-type rj45

no negotiation auto

Standby 30 IP 2XX.XX.XX.254 secondary

Standby 30 priority 110

BGP -SEC

interface GigabitEthernet0/3

description BGP-SEC

ip address 2XX.XX.XX.253 255.255.255.0 secondary

ip address 2X.34.XX.44 255.255.255.0 -- ISP link B

duplex auto

speed auto

media-type rj45

no negotiation auto

Standby 30 IP 2XX.XX.XX.254 secondary

BOth routers are using the IOS version

BOOTLDR: Cisco IOS Software, 7200 Software (C7200P-K91P-M), Version 12.2(31)SB10, RELEASE SOFTWARE (fc2)

now our issue is when i configure the Standby 30 IP 2XX.XX.XX.254 secondary the router througing a error message that

% address cannot equal interface IP address

same if i configure on the BGP Sec its accespting

kindly let me know what might be the root cause

Hi,

If i remove the secondary keyword how the HSRP will chose the redunacy

Hi,

Try to make the addresses XX.58.14.25x the primary addresses and the recreate the hsrp without the 'secondary' keyword.
