Frame Relay: Cannot ping Remote Router (continued)
Possible Problem
Solution
No
broadcast
keyword is found in
frame-relay map
statements.
1.
Use the
show running-config
privileged exec command on
local and remote routers to view the router configuration.
Check
frame-relay map
command entries to see whether
the
broadcast
keyword is specified.
2.
If the keyword is not specified, add the
broadcast
keyword
to all
frame-relay map
commands.
Syntax:
frame-relay map
protocol protocol-address dlci
[
broadcast
]
[
ietf
|
cisco
]
Syntax Description:
•
protocol
—Supported protocols: AppleTalk, DECnet, IP,
XNS, IPX, and VINES.
•
protocol-address
—Address for the protocol.
•
dlci
—DLCI number for the interface.
•
broadcast
—(Optional) Broadcasts should be forwarded to
this address when multicast is not enabled.
•
ietf
—(Optional) IETF form of Frame Relay encapsulation.
Use when the communication server is connected to
another vendor's equipment across a Frame Relay network.
•
cisco
—(Optional) Cisco encapsulation method.
Example:
The following example maps IP address 131.108.123.1 to DLCI
100:
interface serial 0
frame-relay map ip 131.108.123.1 100 broadcast
Note:
By default, the
broadcast
keyword is added to dynamic
maps learned via Inverse ARP
1
.
1.
ARP = Address Resolution Protocol
Frame Relay: Cannot ping End to End
Symptom:
Attempts to
ping
devices on a remote network across a Frame Relay connection fail.
