redundant-interface
Syntax redundant-interface red-ip-int-name
no redundant-interface
Context config>service>vprn
config>service>vprn>sub-if>grp-if
Description This command configures a redundant interface used for dual homing.
Parameters red-ip-int-name — Specifies the redundant IP interface name.
remote-proxy-arp
Syntax [no] remote-proxy-arp
Context config>service>vprn>interface
config>service>vprn>sub-if>grp-if
Description This command enables remote proxy ARP on the interface.
Remote proxy ARP is similar to proxy ARP. It allows the router to answer an ARP request on an
interface for a subnet that is not provisioned on that interface. This allows the router to forward to the
other subnet on behalf of the requester. To distinguish remote proxy ARP from local proxy ARP, local
proxy ARP performs a similar function but only when the requested IP is on the receiving interface.
Default no remote-proxy-arp
secondary
Syntax secondary {ip-address/mask | ip-address netmask} [broadcast all-ones | host-ones]
[igp-inhibit]
no secondary {ip-address/mask | ip-address netmask}
Context config>service>vprn>interface
Description This command assigns an secondary IP address/IP subnet/broadcast address format to the interface.
Default none
Parameters ip-address — The IP address of the IP interface. The ip-address portion of the address command
specifies the IP host address that will be used by the IP interface within the subnet. This address
must be unique within the subnet and specified in dotted decimal notation. Allowed values are IP
addresses in the range 1.0.0.0 – 223.255.255.255 (with support of /30 subnets).
mask — The subnet mask in dotted decimal notation. When the IP prefix is not specified in CIDR
notation, a space separates the ip-address from a traditional dotted decimal mask. The mask
parameter indicates the complete mask that will be used in a logical ‘AND’ function to derive the
local subnet of the IP address. Allowed values are dotted decimal addresses in the range
128.0.0.0 – 255.255.255.252. Note that a mask of 255.255.255.255 is reserved for system IP
addresses.
