multicast-emulation
Disables multicast emulation on each active VC. The default setting for this
feature is enabled. If you disable this feature, you are required to add
protocol static address maps.
Some protocols, such as IPX RIP, will not function on the Frame Relay
interface if multicast-emulation is disabled. The protocol-broadcast feature
also requires multicast-emulation in order to function properly. For more
information, see “Multicast Emulation and Protocol Broadcast” on page 394.
no-pvc
Controls whether the interface is considered active or inactive. If no-pvc is
disabled, the presence of active PVCs on the interface does not affect
whether the Frame Relay interface is considered active or inactive.
notify-fecn-source
Disables setting a BECN bit on the first packet destined to a device from
which the router received a packet with the FECN bit set. See “Circuit
Congestion” on page 399 for more information.
orphan-circuits
Prohibits the use of all non-configured PVC orphan circuits at the interface.
The default setting for orphan circuits is enabled. Disabling orphan circuits
adds a measure of security to your network by preventing unauthorized
entry from a non-configured circuit. However, if you disable orphan circuits,
you are required to add PVCs that will be used on the interface.
protocol-broadcast
Prohibits protocols such as IP RIP from functioning over the Frame Relay
interface. For more information, see “Multicast Emulation and Protocol
Broadcast” on page 394. The default setting for this feature is enabled.
switched-virtual-circuits
Prohibits the use of SVCs.
throttle-transmit-on-fecn
Prohibits the device from
throttling down
the transmission of packets in
response to a packet with a FECN bit set on. The default is disabled. See
“Circuit Congestion” on page 399 for more information.
