create esrp esrp_domain {type [vpls-redundancy | standard]}

Description

Creates an ESRP domain with the specified name on the switch.

Syntax Description


`esrp_domain`	Specifies the name of an ESRP domain to be created. Can be up to 32 characters in length.

Default

The ESRP domain is disabled and in the “Aware” state.

When you create an ESRP domain, it has the following default parameters:

Operational version—Extended
Priority—0
VLAN interface—none
VLAN tag—0
Hello timer—2 seconds
Neighbor timer—8 seconds
Premaster timer—6 seconds
Neutral timer—4 seconds
Neighbor restart timer—30 seconds
VLAN tracking—none
Ping tracking—none
IP route tracking—none

Usage Guidelines

The type keyword specifies the type of ESRP domain when a new ESRP domain is created. The only types supported are vpls-redundancy and standard. Not specifying the optional ESRP domain type results in the creation of an ESRP domain of type standard. The standard ESRP domain is equivalent to the legacy ESRP domain type that was implicitly created. The vpls-redundancy domain type is only specified when redundant access to an MPLS VPLS network is desired.

An ESRP domain name must begin with an alphabetical character and may contain alphanumeric characters and underscores ( _ ), but it cannot contain spaces. The maximum allowed length for a name is 32 characters. For ESRP domain name guidelines and a list of reserved names, see Object Names in the Switch Engine 32.7.1 User Guide .

Each ESRP domain name must be unique and cannot duplicate any other named ESRP domains on the switch. If you are uncertain about the ESRP names on the switch, use the show esrp command to view the ESRP domain names.

You can create a maximum of 128 ESRP domains.

Configuring ESRP-Aware Switches

For an Extreme Networks switch to be ESRP-aware, you must create an ESRP domain on the aware switch, add a master VLAN to that ESRP domain, add a member VLAN to that ESRP domain if configured, and configure a domain ID if necessary.
