Hi,
Maymar Branch has dual connectivity(DXX & Radio). we want the Radio Link as a primary and DXX Link as a secondory & when the primary goes down the secondary takeover but the traffic goes through the DXX link because of less no. of hop counts and Radio Link treated as a secondary link, all the router & switches are running on rip version 2 protocol.

Hi Salman
use offset lists to modify RIP hop counts.
this will allow you to increase number hops seen from DXX.

Hi Sam,
Thanks for your helpful response this will work on only one condition when i shutdown the DXX interface on Maymmar branch did this work only on failover condition .
I need to know one more query from you i.e
1) If i run RIP v2 on Maymmar how would i be make radio link as primary and DXX Link as secondary link.
Is there any command in RIP v2 to make primary route and secondary route. I also attached Maymmar router configs.

Hi Salman
Under routing process add
router rip
offset-list 10 out 5 s0/2/0
offset-list 10 in 5 s0/2/0
!
access-list 10 permit x.x.x.x y.y.y.y
the above will add a metric of 5 when sending via ur backup link and 5 when receiving via backup link.
x.x.x.x is the Prefix u wish to apply this offset to.
do sh ip route before and after this to validate the changes.

Hi Sam,
After your recomendation this was the result i found
Trace from Branch Switch to Maymmar server
BranchSwitch#traceroute 10.0.14.0
Type escape sequence to abort.
Tracing the route to 10.0.14.0
1 10.254.1.2 80 msec 80 msec 48 msec
2 10.0.2.2 60 msec 56 msec 64 msec
3 10.254.1.105 92 msec * 76 msec
Trace from Maymmar to Branch Switch server
Maymar#traceroute 10.20.0.1
Type escape sequence to abort.
Tracing the route to 10.20.0.1
1 10.254.1.89 60 msec 48 msec 32 msec
2 10.20.3.1 88 msec * 92 msec
I want Maymmar traffic goes from radio link not secondary link.
