The peer mac-limit command limits the number of MAC advertisement routes received from a peer.
The undo peer mac-limit command restores the default configuration.
By default, the number of MAC advertisement routes received from a peer is not limited.
peer { group-name | ipv4-address } mac-limit number [ idle-forever | idle-timeout times ]
undo peer { group-name | ipv4-address } mac-limit
| Parameter | Description | Value |
|---|---|---|
| group-name | Specifies the name of a peer group. | The name is a string of 1 to 47 case-sensitive characters, with spaces not supported. When double quotation marks are used around the string, spaces are allowed in the string. |
| ipv4-address | Specifies the IPv4 address of a peer. | The value is in dotted decimal notation. |
| number | Specifies the maximum number of MAC advertisement routes received from a peer. | - |
| idle-forever | Indicates that a terminated connection is not automatically re-established after the number of routes exceeds the maximum limit. | - |
| idle-timeout times | Specifies a timer for automatically re-establishing a terminated connection after the number of routes exceeds the maximum limit. No connection will be automatically re-established before the timer expires. | The value is an integer that ranges from 1 to 1200, in minutes. |
Usage Scenario
A BGP-EVPN instance may import many invalid MAC advertisement routes from peers. In this case, To prevent these routes from occupying a large proportion of MAC advertisement routes, run the peer mac-limit command to configure the maximum number of MAC advertisement routes allowed to be received from each peer.
Precautions
After this command is run, excessive routes in the BGP-EVPN address family view may be discarded.
When the number of MAC advertisement routes exceeds the maximum limit, run the undo peer mac-limit command. The device then receives routes from each peer and adds them to the EVPN routing table.
