The set routing prefix-list ipv4 command configures a standard community list to match a specific community number attribute. Community-list is a named list of regular expressions. They are used to match the community number attributes in the routes for inclusion in, or exclusion from route policies. command creates an IPv4 prefix list or an entry in an IPv4 prefix list.

The delete routing prefix-list ipv4 command removes the standard community list configurationcommand deletes an IPv4 prefix list or an entry from an IPv4 prefix list.


Command Syntax

set routing prefix-list ipv4 <ip-prefix-name> description <wildcard>delete routing community-list standard <community-list-name>{deny|permit} [local-AS|no-advertise|no-export|internet|<community>> [seq <sequence-number>] <ipv4/prefixlen> [ge <greater-equal-value>] [le <less-equal-value>]

delete routing prefix-list ipv4 <ip-prefix-name>[seq <sequence-number>] <ipv4/prefixlen> [ge <greater-equal-value>] [le <less-equal-value>]


Parameter

Parameter

Description

<community-list-name>

Specifies the name of the community list that matches a route.

{deny|permit}

Specifies whether the route is available for further processing when there is a match.

{local-AS|no-advertise|no-export|internet|<community-numer>}

Optional. Specifies BGP community type, it can be one of following BGP communities:

  • local-AS: a BGP community that restricts routes to your confederation’s sub-AS.
  • no-advertise: a BGP community that is not advertised to anyone.
  • no-export: a BGP community that is not advertised to the eBGP peer.
  • internet: a BGP community that matches all routes.
    • <community-numer>: specifies the communities value

    <ip-prefix-name>

    		Specifies the name of an IPv4 prefix list.

    seq <sequence-number>

    		Optional. Specifies the sequence number of an entry in the IPv4 prefix list.

    <ipv4/prefixlen>

    		Specifies an IP address/prefix lenghth.
    ge <greater-equal-value>Optional. Specifies the lower threshold of the mask length. If ge greater-equal-value and le less-equal-value are not specified, the value of mask-length is the mask length.
    le <less-equal-value>Optional. Specifies the upper threshold of the mask length. If ge greater-equal-value and le less-equal-value are not specified, the value of mask-length is the mask length.


    Usage Guidelines

    The BGP community list can be either standard or expanded. The standard BGP community list is a pair of values (such as 100:100) that can be tagged on a specific prefix and advertised to other neighbors or applied on route
    ingress.
