Sorry I saved the last postin in html

I have a router eith the following configuration in fa0.1 and fa1.2

interface fastethernet0.1

encapsulation dot1q 10

ip address 10.10.10.3 255.255.255.0

interface fastethernet1.2

encapsulation dot1q 15

ip address 10.10.15.3 255.255.255.0

and routing table as follows:

c 10.10.10.0 is directly connected fastethernet0.1

c 10.10.15.0 is directly connected , fastethernet1.2

s* 0.0.0.0/0[1/0 via 10.10.15.1

I need to know, if I can have second static default route to 10.10.10.1 ? like 0.0.0.0/0[1/0] via 10.10.10.1 , if not how can I rell router to route some packest to 10.10.10.1 and some others to 10.10.15.1 ,

these interfaces are connected to the next hop router which is asa in this case

Hi, Yes you can do that. You can have mutiple static/default routes pointing to different next hop ip.

The router bydefault does the per-destination load balancing. You can change the behaviour on the router to do the per-packet loadbalancing.

Hello Amit,

maybe I should clarify more,

these interfaces are connected to the the subinterfaces on a next hop device which is ASA, when I add ip route 0.0.0.0 0.0.0.0 10.10.10.1

I can ping an address after ASA "public:66.128.95.241" but i can't ping another public "66.128..95.145"

Whn I add ip route 0.0.0.0 0.0.0.0 10.10.10.15 I can ping public 66.128.95.145 , when I add both I can't ping either of those public addresses.

Best Regards,
