local-proxy-arp
Syntax [no] local-proxy-arp
Context config>service>vprn>if
Description This command enables local proxy ARP. When local proxy ARP is enabled on an IP interface, the
system responds to all ARP requests for IP addresses belonging to the subnet with its own MAC
address, and thus will become the forwarding point for all traffic between hosts in that subnet. When
local-proxy-arp is enabled, ICMP redirects on the ports associated with the service are automatically
blocked.
Default
no local-proxy-arp
loopback
Syntax [no] loopback
Context config>service>vprn>if
Description This command specifies that the associated interface is a loopback interface that has no associated
physical interface. As a result, the associated interface cannot be bound to a SAP.
When using mtrace/mstat in a Layer 3 VPN context then the configuration for the VPRN should have
a loopback address configured which has the same address as the core instance's system address
(BGP next-hop).
Default None
proxy-arp-policy
Syntax [no] proxy-arp-policy policy-name [policy-name...(up to 5 max)]
Context config>service>vprn>if
This command enables a proxy ARP policy for the interface.
The no form of this command disables the proxy ARP capability.
