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
