Configuring IP RIP Filters
Page 25-35
5. The following prompt displays:
IP network mask (default: 255.255.255.0) :
Enter the IP network mask of the network that is to be allowed or blocked by the filter
(or just press
(or just press
Enter
to use the default mask of 255.255.255.0). Note that the default mask
will vary depending on the class of the IP address you entered above.
6. If the Group:VLAN is a
WAN
routing service, the following prompt displays:
Do you wish to apply this filter to a specific WAN endpoint? (n): y
Frame Relay VC or PPP Peer {vc(v), peer(p)} (v):
Frame Relay VC or PPP Peer {vc(v), peer(p)} (v):
Enter
y
to apply this filter to a specific WAN endpoint.
7. The following prompt displays:
Frame Relay VC or PPP Peer {vc(v), peer(p)} (v):
Enter
v
(or just press
Enter
) to apply this filter to a Frame Relay VC.
Enter
p
if you want to apply this filter to a PPP Peer.
8. If you choose to apply the filter to a Frame Relay VC, this prompt will appear:
Slot/port:
Enter the slot and port numbers to which you want to apply this filter.
9. You will then be prompted for the virtual circuit (VC) to which to apply this filter:
VC:
Enter the VC to which you want to apply this filter.
10. If you choose to apply a filter to a PPP Peer, this one prompt will appear:
Peer ID:
Enter the Peer ID to which you want to apply this filter.
A message will appear indicating that the filter was successfully added.
IP RIP Filter Precedence
Whenever you use multiple “allow” filters you must first define a filter to block all RIPs. Then,
any other “allow” filters of the same type must be at least as specific in all areas in order for
the filters to work. Note that filtering precedence is related only to “allow” filters. Multiple
“block” filters can be defined with varying specificity in each of the areas of the filter. The
filtering done by the configurable parameters (Address/Mask) in the “allow” filter must be at
least as specific as the filtering defined in the “block” filter.
