Article ID: KB6070 KB Last Updated: 02 Jul 2010Version: 3.0
Summary:
HSRP and VRRP routers not exchanging Hello Packets Properly
Symptoms:
HSRP needs to have connectivity to its HSRP peer to send and receive hellos VRRP' needs to have connectivity to its' VRRP peer to send and receive hellos HSRP routers becoming both active VRRP routers becoming both active HSRP not receiving hellos from peer HSRP not receiving hellos from peer HSRP not behaving working properly when interfaced with the netscreen directly VRRP' not behaving working properly when interfaced with the netscreen directly
Solution:

A switching fabric is required when a router is interfaced with a NetScreen. This is so that the router interfaces can exchange hello packets. If the NetScreens are connected to a switching router then it is also possible to have a trunk between the routers so they can use it to exchange hello messages.

Here is the problem or goal:

  • HSRP routers becoming both active
  • VRRP routers becoming both active
  • HSRP not receiving hellos from peer
  • HSRP not receiving hellos from peer
  • HSRP not behaving working properly when interfaced with the netscreen directly
  • VRRP not behaving working properly when interfaced with the netscreen directly

Problem Environment:

  • HSRP needs to have connectivity to its HSRP peer to send and receive hellos
  • VRRP needs to have connectivity to its VRRP peer to send and receive hellos
