Frame Relay: Cannot ping Remote Router (continued)
Possible Problem
Solution
An access list was
misconfigured.
Use the
show access-list
privileged exec command to see
whether there are access lists configured on the router.
1.
If there are access lists configured, test connectivity by
disabling access lists using the
no access-group
global
configuration command. Check whether connectivity is
restored.
2.
If connections work, re-enable access lists one at a time,
checking connections after enabling each access list.
3.
If enabling an access list blocks connections, make sure
that the access list does not deny necessary traffic. Make
sure to configure explicit
permit
statements for any traffic
that you want to pass.
4.
Continue testing access lists until all access lists are
restored and connections still work.
5.
