Traffic to the nodes behind TE Tail end can be loadshared between IGP path and TE tunnel with "autoroute announce" configured on TE tunnel.

But is there any way i can avoid to take a TE tunnel path for nodes behind TE tunnel.

thanks in advance...

Once you use autoroute announce, the TE tunnel looks to IP like a new link for all the destinations behind the tunnel endpoint. From this point of view your question could be rephrased to: "How can I avoid to send IP packets towards a certain destination over a particular interface?"

You can use

1) static routing

2) Policy based routing

3) class-based tunnel selection

4) make the tunnel worse than the IGP path (e.g. with relative metric +1)

All have their pros and cons depending on your specific network requirements.

Hope this helps! Please use the rating system.
