master-icmp-reply Configuring VRRP
Enterasys Matrix DFE-Gold Series Configuration Guide 21-65
Example
ThisexampleshowshowsetaVRRPpriorityof200onVLAN1,VRID1:
Matrix>Router(config)#router vrrp
Matrix>Router(config-router)#priority vlan 1 1 200
master-icmp-reply
UsethiscommandtoenableICMPrepliesfornon‐ownermasters.
Syntax
master-icmp-reply vlan vlan-id vrid
no master-icmp-reply vlan vlan-id vrid
Parameters
Defaults
None.
Mode
Routercommand,Routerconfiguration:Matrix>Router(config‐router)#
Usage
ThiscommandprovidestheabilityforthevirtualroutermastertorespondtoanICMPechoeven
ifitdoesnot“own”thevirtualIPaddress.Withoutthisfunction,thevirtualroutercanonly
respondtoanICMPechowhenthevirtualIPaddressmatchestherealIPaddressofthe
interface.
Therefore,whenthebackuproutertakesover,therewouldbenodevicethatwouldanswerthe
ICMPechoforthatvirtualIP(becauseonlytheprimarywasconfiguredwiththematchingreal
IP).Withmaster‐icmp‐replyenabled,managementstationsthatuse“ping”topolldeviceswillbe
able
to“see”thatthevirtualrouterisavailablewhenthebackuprouterassumestheroleofmaster.
The“no”formofthiscommanddisablesmasterICMPreplies.
Example
ThisexampleshowshowenablemasterICMPrepliesonVLAN1,VRID1:
Matrix>Router(config)#router vrrp
Matrix>Router(config-router)#master-icmp-reply vlan 1 1
vlanvlan‐id SpecifiesthenumberoftheVLANonwhichtoenablemasterICMP
replies.ThisVLANmustbeconfiguredforIProutingasdescribedin
