Duplicate Entry in routing table

[shikhar_1]

Hi All,

This is regarding the issue reported by application team and claimed that they are facing some intermittent access problem, while accessing the DB server from their appl server.

I have checked but did not find any issue except duplicate entry in the routing table and issue occured after adding one route as shown below.

127.0.0.0             127.0.0.1          U     0    lo0       32808

default               135.179.32.1       UG    0    lan6       1500

So my query is that can we have duplicate entry in the routing table or adding a route can affect the accessing issue.

You need to delete  this route. 

135.179.40.0          135.179.44.1       UG    0    lan3       1500    <----- This route has been added recently.

135.179.40.0          135.179.44.1       UG    0    lan3       1500    <----- This route has been added recently.

Your server have already the route handled by this interface.

135.179.44.0          135.179.44.88      U     6    lan3       1500

I assume that 135.179.44.1 is your gateway to talk to other network segment. 

But it still not clear what is who is app and who is db server.  You have a lot of sub interface define too.
