FAQ - why it will show peer down but the double machine business normal when E200 inquires the HRP

Publication Date:  2012-10-09 Views:  92 Downloads:  0
Issue Description
When inspecting E200 through “display HRP verbose” inquires the HRP information and finds a display “Peer down”, but the double machine business is normal, there whether be any other influence?
display hrp verbose
interface : Ethernet1/0/1, vrrp id : 14 Peer Down
Alarm Information
Handling Process
In the previous version of 0337, VRRP message needs to do packet filtering and needs to add a rule in the corresponding domain ACL:
acl number 3003
rule 10 permit 112
After add this ruler, can solve the peer down problem.
If the interface doesn’t transmit HRP data, the heartbeat interact through the HRP interface, peer down state, don't change VGMP’s priority, is will not affect the double machine business, double machine’s primary/secondary state is still correct.
The versions after 0337 EU200 VRP3.30 default VRRP message can pass through, do not need to do relevant ACL configuration.
