Hello,
i have 2x CCR and both of them are connected to my provider same switch. and on both of them i have configured bgp and vrrp and both of them are announcing same prefixes.
but the issue is incoming traffic is available on both router however i want only force traffic to my master router and if it goes down traffic goes from second router.
i tried bgp prefix prepend and MED but they did not work and after them i still have data on second router.
any idea?
Thank you.
I had the same issue with one of our CCR vrrp-cluster peering a SilverPeak VXOA appliance. It turned out that the appliance wasn’t interpreting MEDs correctly.
I solved it with manually adjusting advertised distances. Not the smart way but it worked.
Just to be sure - your two CCRs share the same AS number and are locally connected to each other and exchanging iBGP?

Hello,
both of my routers has same AS and esbtalished bgp with same router with my carrier.
also i have ospf between my routers (not physcally) but with vlan.
so hwo can i chahnge distance?
thanks
In routing filters - as you already did with prepend and MED.

Hi,
in bgp actions tab i look for distance there was nothing and then i check actions that and use set distance but no sucess.
thanks
You could cheese it.
Its not the correct way but it should work until you can get it working properly.
In vrrp there is a script feature. on master and on backup.
when the second router is on backup disable the bgp session to the provider, when on master you can enable it again.
what size is the range you are advertising to your provider?
if for example it’s a /23
advertise the two /24’s on R1 and advertise the /23 on router 2, this will force traffic coming in on router 1.
This is not a good way of doing it as things have the potential to get messy, real quick. I’ve just today setup a near identical setup and posted it to the forums, however waiting for MT to approve the post. Will linkback here when it’s up.
