Parameters for
match clauses
Parameter Description
MAtch Modifies the match clause in the entry. The match clause determines
which routes or BGP update messages the entry applies to. A route
map entry can have zero or one match clauses. An entry without a
match clause matches all routes or updates.
ASPath The ID number of an AS path list. An update message matches the
route map entry if its AS path attribute matches the AS path list. To
configure an AS path list use the add ip aspathlist command on
page 2-40.
Valid when filtering BGP routes.
Default: no default
COMmunity The ID number of a community list. An update message matches the
route map entry if its community attribute matches the community
list.To configure a community list use the add ip communitylist
command on page 2-42.
Valid when filtering BGP routes.
Default: no default
EXAct Whether the community attribute in an update message must
precisely match the route map’s community list. Only valid when you
specify both match and community.
Default: no
YES An update message only matches the route map entry
if its community attribute contains all the communities
specified in the community list and only those
communities.
NO An update message still matches the route map entry if
its community attribute contains all the communities
specified in the community list plus extra communities.
INTerface A router or switch interface. A route matches the route map entry if
its next hop is out the specified interface. Valid interfaces are:
eth (such as eth0, eth0-1)
ATM (such as atm0.1)
PPP (such as ppp0, ppp1-1)
FR (such as fr0, fr0-1)
X.25 DTE (such as x25t0, x25t0-1)
VLAN (such as vlan1, vlan1-1)
To see a list of interfaces currently available, use the show interface
command.
Valid when filtering OSPF routes.
Default: no default
MED The update message’s Multi_Exit_Discriminator attribute. EBGP uses
the MED to determine the optimal path for reaching the advertised
prefixes. A lower metric indicates a preferred path. IBGP does not use
this attribute. An update message matches the route map entry if its
MED attribute matches this value.
Valid when filtering BGP routes.
Default: no default
