Filtering IP Routes set ip route filter 2-63
Software Version 2.7.5
C613-10454-00 REV A
DIrection Whether the router or switch applies this filter to routes that the
routing protocol receives or routes that it advertises. The routing
protocol is specified using the protocol parameter.
Default: both
RECeive The router or switch applies this filter to routes that the
routing protocol receives, to determine whether to
write those routes into the RIB.
SENd The router or switch applies this filter to routes, to
determine whether the routing protocol will advertise
the routes.
Note that the nature of the OSPF protocol affects how
route filtering works on OSPF Link State Advertisement
(LSA). A route filter with direction=send only matches
Autonomous System (AS) external routes. Also, the
router or switch ignores the interface parameter, so it
applies the filter on all interfaces.
BOTH The router or switch applies this filter to determine
which routes to write into the RIB and which routes to
advertise.
INTerface The interface to which the filter applies. The router or switch only uses
this filter on routes that are received on this interface, or that will be
advertised out this 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.
If protocol=ospf, the router or switch ignores this setting when
filtering routes to advertise.
Default: no default (the router or switch applies this filter to routes on
all interfaces)
NEXThop The IP address of the next hop router. If you specify this, the router or
switch applies this filter to routes that specify this next hop.
Default: no default
POLIcy The value of the route’s Type of Service, from 0 to 7. The filter matches
routes with this TOS setting.
Default: no default
PROTocol The routing protocol to which the filter applies. If direction is receive,
then protocol specifies the routing protocol that receives the route
information. If direction is send, then protocol specifies the routing
protocol that advertises the routes.
Default: any
