Route Precedence

Few days back one of my friend ask me, if we have three routes

10.10.10.0/24 via bgp
10.10.10.0/24 via ospf
10.10.0.0/16 via eigrp

which route will take for 10.10.10.1??

Then I start searching  the  answers on net and luckily find a solution.  

Now the basic funda is,

Route selection precedence is as follows

1. Most Specific route
2. AD value
3. Metric


Now here most specific routes are

10.10.10.0/24 via bgp
10.10.10.0/24 via ospf

Now AD value will come in the picture as tie breaker....

Take a look at the following Table for AD values

Default Administrative Distances
Connected 0
Static 1
eBGP 20
EIGRP (internal) 90
IGRP 100
OSPF 110
IS-IS 115
RIP 120
EIGRP (external) 170
iBGP 200
EIGRP summary route 5


Now the Answer is a question, Which BGP route was that, EBGP or IBGP??

If it is IBGP (AD value: 200), OSPF routes will get precedence…. Else it gonna take BGP routes (AD Value: 20)
