only one route in routing table Eigrp

I have created one scenario
1) there are two Eigrp process running on each router
2) there is one loopback address configured on Router A, & published in both Eigrp process.

As Eigrp load balance, but loopback  route is present from only one link.

Can any one explain why it is not present from both Links.

Suryakant,

for load balancing you don't need to have two EIGRP processes. Most probably you have enabled one link in first process and the other link in the second EIGRP process. EIGRP will check routes learnt from both the AS and if everything is comparable, then it will install the route from the lower AS

Use single EIGRP AS, enable both links in EIGRP along with the loopback and then Router B will have two paths to reach Router A loopback

For reference, go through the document:

Hope it helps

if you want to do load balancing there is NO need to run 2 routing instances.

just enable EIGRP on both interfaces, and it will select the best route as per the criteria of EIGRP.

you should make all the variable same on both links and EIGRP will install both routes in routing table and will start doing the load balancing.
