Juniper JUNOSE 11.2.X IP SERVICES, Configuration Manual

Page: 52 / 356

•
Use the no version to delete an IP access list (no other options specified), the specified
entry in the access list, or the log for the specified access list or entry (by specifying
the
log keyword).
•
See access-list.
default-information originate
•
Use to enable RIP, OSPF, or BGP to advertise a default route (0.0.0.0/0) that exists
in the IP routing table.
•
If you specify the always option for OSPF, OSPF generates a default route, if it does
not exist in the IP routing table and advertises it.
•
Use to generate a default route to an IS-IS domain.
•
Example
host1(config-router)# default-information originate
•
Use the no version to disable advertisement of the default route.
•
See default-information originate.
ip as-path access-list
•
Use to define an AS-path access list to permit or deny routes based on the AS path.
•
Each access list is a set of permit or deny conditions for routes based on matching a
route's AS path to a regular expression. If the regular expression matches the
representation of the AS path of the route as an ASCII string, the permit or deny
condition applies. The AS path does not contain the local AS number.
•
The AS path allows substring matching. For example, the regular expression 20 matches
AS path = 20 and AS path = 100 200 300 , because 20 is a substring of each path. To
disable substring matching and constrain matching to only the specified attribute
string, place the underscore (
_ ) metacharacter on both sides of the string; for example,
_20_ .
•
Use the neighbor filter-list command to apply the AS-path access list. You can apply
access-list filters to inbound and outbound BGP routes. You can assign weights to
routes matching the AS-path access list.
•
Example
host1(config)# ip as-path access-list 1 permit ^\(
•
Use the no version to remove the AS-path access list; all entries that belong to this list
are removed.
•
See ip as-path access-list.
ipv6 access-list
•
Use to define an IPv6 access list to permit or deny routes based on the prefix.
•
Each access list is a set of permit or deny conditions for routes based on matching a
route's prefix.
