Hi all,
I am using a redhat 8.x linux box configured with
zebra routing software which is also configured with ospfd
I have 2 backbone routers running
ospf connected to different isp's
I have 3 local routers also running ospf within
themselfs and also with the 2 backbone routers (all are linux
boxes)
router A - backbone router 1
router B - backbone router 2
router C - local router 1 (has 3 subnets routed via
it)
router D - local router 2 (has 2 subnets routed via
it)
router E - local router 3 (has 5 subnets routed via
it)
my pc connected to local router D whose
default gw is router A
In our local router we are trying to have policy
routing
without any policy routing when I try to trace ip
in the subnet behind router C the next hop is learnt by the ospf routing entry
in the main table and the packet is landing in router C while when I try to
trace yahoo.com the packet is landing into router A and reaching
yahoo.com
but when I am trying to deploy policy route-map in
which if I say packets originating from X network's default gw is router B I
find that the packets are always landing on the router B even if the destination
is know network via ospf.
I deployed policy routing as below in my linux box
(router D)
echo "200 GWA" > >
/etc/iproute2/rt_tables
/sbin/ip rule add from x.x.x.x/28 table
GWA
/sbin/ip route add default via y.y.y.1 table
GWA
when I try to see the main table by giving the
command below
ip route list table main
I find all the ospf routes in that table ended with
the default gw entry
when I see the table GWA I find only the default
next hop entry ie., router B (y.y.y.1)
is there any way of dynamically updating even in
GWA table with the ospf entries followed by default next hop
y.y.y.1
Kindly help me in this regard
