RDN(config-if)#no ip access-group <group number> access-list
[extended | standard] <list number>
where:
group number is the ip access group
extended or standard is selected for an access list
list number is the access list number
5. Execute the debug ip packet command to determine whether the router is
receiving packets.
6. If the router is receiving packets an access list is probably filtering packets. To
isolate the problem list, enable access lists one at a time until packets are no
longer forwarded by using the distribute-list command in Router
Configuration mode, as shown in the following example:
RDN(config)#router <protocol>
where protocol is the routing protocol used.
RDN(config-router)#distribute-list [extended | standard] | <list number>
where:
extended or standard is selected as the type of distribute list
list number is the access list number.
7. Check the access list to see whether it is filtering traffic from the source router.
If it is, alter the access list to allow the traffic to pass. Enter explicit permit
statements for traffic that you want the router to forward normally.
8. To enable the altered access list to see whether packets continue to pass
normally, use the ip access-group access-list command in Router
Configuration mode, as shown in the following example:
RDN(config-router)#ip access-group <group number> access-list <list
number>
where:
group number is the ip access group
list number is the access list number
