Frame Relay Commands
Once chosen as static, no inverse ARP will be sent out by default. A free inverse ARP request
(similar to above) can be requested by this command.
Once chosen as static, this DLCI can be made to respond to a broadcast bootp message entering on
this DLCI from the frame‐relay network. Non‐broadcast bootp will still be sent to the local DHCP
server or relayed to the IP helper address server..

Syntax of the "no" Form
Use the no command to delete the DLCI from the specified sub‐interface:
no frame-relay interface-dlci dlci-num
Mode
Sub‐interface configuration:
9-86 Configuring Frame Relay
Notes: The remote site must support sending inverse-arp responses or the interface will come
down.
An inverse arp is sent from the XSR at a rate of 1 every 4 seconds. It is not configurable.
DLCI number for the sub‐interface, ranging from 16 to 1007. For the Point‐
to‐Point (P2P) sub‐interface type, only one DLCI is allowed. For Point‐to‐
Multi‐Point (P2MP) you can configure multiple DLCIs.
Sends inverse ARP request and ignores a response. This parameter occurs
for non‐static IP mapping. P2P sub‐interfaces will generate a free inverse arp
to allow the remote side to learn the IP address of this sub‐interface. This
parameter is useful only for P2P sub‐interfaces, since Point‐to‐MultiPoint
interfaces withdynamic IP resolution will always inverse ARP to learnthe
remote nodeʹs IP address. Omitting this value in a P2P sub‐interface
prevents sending an inverse‐arp request. An inverse‐arp responseis always
sent when an inverse‐arp request is received. Broadcast bootp is not
supported in dynamic mode. Allbootp request in this mode are forwarded.
Protocol type to set static IP address to DLCI mapping.
Static IP address of peer node. No address checking done.
Respond to a broadcast bootp request with static IP address (used for
Remote Auto Install Central Site).
Sends inverse ARP request. Response is ignored. Valid for both MP2P &
P2P sub‐interfaces.
nn refers to the duration that a DLCI under a P2P interface will wait with no
traffic being received before sending an inverse‐arp packet to confirm that
the remote side is still present. The nn range is 10 to 600 seconds.
