On the 7210 SAS, users can enable or disable proxy-ARP and proxy-ND commands for all EVPN services configured on the node; however, the option to enable or disable proxy-ARP or proxy-ND per service is not available.
Use the following syntax to enable or disable proxy-ARP or proxy-ND capability per node.
— configure>service>system>[no]evpn-proxy-arp-nd
If the per-node evpn-proxy-arp-nd command is disabled, it is not possible to enable the proxy-arp or proxy-nd command per service, and proxy-arp or proxy-nd is disabled for all EVPN services on the node.
When the evpn-proxy-arp-nd command is enabled, the user must run the following sequence of commands to disable the per-node proxy-arp and proxy-nd commands, if required:
Run the config>service>system>no evpn-proxy-arp-nd command.
Run the config>service>vpls>no proxy-arp command.
Run the config>service>vpls>no proxy-nd command.
The following example shows the command usage to enable proxy-arp and proxy-nd for all services, with all parameters set to default values:
--------------------------------------------------------------------------
configure
service
system
evpn-proxy-arp-nd
exit
exit
service
vpls 100
proxy-arp
no age-time
dup-detect window 3 num-moves 5 hold-down 9
no dynamic-arp-populate
... (so on for other parameters supported under proxy-arp)
no shutdowm
exit
proxy-nd
no age-time
dup-detect window 3 num-moves 5 hold-down 9
no dynamic-nd-populate
... (so on for other parameters supported under proxy-nd)
no shutdowm
exit
exit
exit
--------------------------------------------------------------------------
When the user runs the config>service>system>evpn-proxy-arp-nd command, the software automatically runs a no shutdown command for proxy-arp and proxy-nd for all services. Similarly, when the user runs the config>service>system>no evpn-proxy-arp-nd command, the software automatically runs a shutdown command for proxy-arp and proxy-nd for all services.
When the evpn-proxy-arp-nd command is enabled, the proxy-arp or proxy-nd command is enabled for all services and cannot be disabled for individual services. Configuring service-specific proxy-arp or proxy-nd command parameters is supported only when the evpn-proxy-arp-nd command is enabled.
