Hi Dojs,

It has been a long long time since I have used X.25 on a Cisco router.

I wouldn't recommend load-balancing over X.25 with another media as X.25 is slow but if you had to use X.25 as a failover interface, I would use something like a 'floating static' that only 'kicks' in when your main link fails?

CheerZ and good luck

yes i know this is very old rs, but here have lot of business that wants use...

So, now i receive a follow idea: We will buy another x.25, and the idea is plug both in 2800. My question is:
- How i can make a failover with this i will set this in interface cfg?

Like standy be?

Hi Dojs,

I have have two paths to the same route and BGP is used for the main path.  When the main path fails a 'floating' static kicks in and routes the traffic down the second path I.e.

ip route 10.0.0.0 255.255.0.0 172.16.1.1 25 name floater

BGP has an administrative distance of 20 by default, which is better that the administrative distance for the 'floating' static which I set as 25, so when BGP or the main path dies then the 'floating' static is installed into the routing table and sends traffic down the second path.

CheerZ and good luck
