metric if the source was pre-configured and can be modified. The valid values are 1 to 15.
•

protocol. Only permitted routes are redistributed.

IP Access Control Lists
. When used for route filtering, the only
fields in an access list that get used are:
– Source IP Address and netmask
– Destination IP Address and netmask
– Action (Permit or Deny)
All other fields (source and destination port, precedence, tos, etc.) are ignored.
The source IP address is compared to the destination IP address of the route. The source IP netmask in
the access list rule is treated as a wildcard mask, indicating which bits in the source IP address must
match the destination address of the route.
NOTE:
A 1 in the mask indicates a Don’t Care in the corresponding address bit.
When an access list rule includes a destination IP address and netmask (an extended access list), the
destination IP address is compared to the network mask of the destination of the route. The
destination netmask in the access list serves as a wildcard mask, indicating which bits in the route’s
destination mask are significant for the filtering operation.
•
Redistribute
— Enables or disables the redistribution for the selected source protocol. This field has to
be enabled in order to be able to configure any of the route redistribution attributes.
