I'm not sure I understand your point. Assume the following topology:
[R1] [R2]
| |
| |
\----------------------/
|
[HOST]
The two border routers are R1 and R2 and each have a connection to an
ISP. HSRP is configured to track the WAN link. The default gateway on
the host is the HSRP standby ip address. If either WAN link goes down,
the relevant router--because it is tracking the WAN link--will notify
the other router that it is no longer eligible and the other router will
take over.
Why are you saying that the perceived uptime to the host would not
increase using this method? As I see it, unless both links go down, the
downtime would be quite minimal.
Thanks,
John

Come on guys, Think about it for a minute. Do you really think the
router
is failing, or is his downtime caused by the wan link? HSRP won't
significantly increase your uptime if the wan link is failing and he
has to
manually change his server's IP/default gateway to switch to the other
link.
A diferent way to think of it... If you had a car with no brakes and
a
broken tail-light, which would you fix first?

Run HSRP between the two cisco routers and then point your default
gateway
to the VIP address.

Subject: TWO ISP AND ONE FAILURE [7:36371]
Hello i have a frecuent porblem with one of my isp, i have two cisco
routers
and each one to different isp. Frequentily i have to change the gateway
of
one of my servers, because one isp is failure.
I want to know if with one of BGP, OSPF, RIP, NAT or other protocol i
could
do the change automatically to the other active isp.
It happening me right now. And when i have to do that i have to reset
one of
my servers.. :S. Is a costs operatrion its a mail server.
So if somebody knows how to resolve between routers with different isp
each
one, how to route accross the other good gateway.
Thnx in advance
Yassl
