Hi All,
in cisco web
... because when HSRP is enabled, Internet Control Message Protocol (ICMP) redirect messages are disabled. ...
this sentence is taken from :
http://www.cisco.com/en/US/tech/tk648/tk362/technologies_white_paper09186a00800a9829.shtml
and also :
... Proxy ARP breaks when use-bia is configured. A standby router cannot cover for the lost proxy ARP database of a failed router...

http://www.cisco.com/en/US/tech/tk648/tk362/technologies_tech_note09186a0080094a91.shtml
but, when I configured HSRP like this one below :
ROUTER-A#show run int fa0/0
Building configuration...
Current configuration : 190 bytes
!
interface FastEthernet0/0
description LAN between ROUTER-A and ROUTER-B
ip address 172.16.1.129 255.255.255.192
speed auto
half-duplex
standby use-bia
standby 1 ip 172.16.1.100
standby 1 priority 105
end
ROUTER-A#show standby
FastEthernet0/0 - Group 1
Local state is Active, priority 105, use bia
Hellotime 3 sec, holdtime 10 sec
Next hello sent in 1.262
Virtual IP address is 172.16.1.100 configured
Active router is local
Standby router is 172.16.1.130 expires in 8.916
Virtual mac address is 0007.ebae.d020
5 state changes, last state change 00:12:08
The output of show ip int fa0/0 is like this :
ROUTER-A#show ip int fa0/0
FastEthernet0/0 is up, line protocol is up
Internet address is 172.16.1.129 255.255.255.192

Am I missing something ?
