Parameter | Description |
<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. greater-equal-value must meet the following requirement: prefixlen ≤ greater-equal-value ≤ less-equal-value ≤ 32. If only ge is configured, the mask ranges from greater-equal-value to 32. |
| 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.
Example
- Here is an example of a standard community list filter:
...
less-equal-value must meet the following requirement: prefixlen ≤ greater-equal-value ≤ less-equal-value ≤ 32. If only le is configured, the mask ranges from prefixlen to less-equal-value. |
Example
Configure the IP prefix list named p1 to permit only the routes with the mask length ranging from 17 to 18 on the network segment 10.0.0.0/8.
