[nsp] HSRP and Netscreen Firewall

[Ian Terry]

Hello, 

We have a customer who has dual peering links with two different
providers that are maintained via Cisco 7500 routers

Behind the routers the customer has Netscreen Firewalls that are
configured to operate in transparent mode.

The routers are running HSRP and unfortunately the multicasting of HSRP
does not appear to be allowed through the Firewall - even though
Netscreen claim that it should. If the Firewall is removed, then HSRP
works fine. 

Does anybody have an experiences similar to this ? 

regards, Ian
