Hi Everyone
Can someone help to interprept the following
sh ip route 10.234.241.22
Routing entry for 10.234.241.16/28
Known via "connected", distance 0, metric 0 (connected, via interface)
Redistributing via eigrp 30, bgp 65037
Advertised by bgp 65037
Routing Descriptor Blocks:
* directly connected, via Vlan20
Route metric is 0, traffic share count is 1
May i know , wat does the Redistributing via eigrp 30, bgp 65037 mean ? Someone help to advice. THanks
Thanks

HI, [Pls Rate if Helps]
The route 102.34.241.22 is Advertised to the network via parent "BGP 65037" Autonomous System.
This is redistributed into Eigrp 30 - Autonomous System.
Eg:
router bgp 65037
network 10.234.241.22
router eigrp 30
redistribute bgp
If you can post your configuration more we can still help more.
PLS Rate if Helps

I agree that the output indicates that the subnet is advertised by BGP in AS 65037. I am not sure that it is redistributed into EIGRP and believe that there is a network statement for this network under EIGRP 30.
I agree that posting the config would allow us to to determine more exactly what it is. It would also be interesting and perhaps helpful if you post the output of show ip protocol.

Hi ,
*** Redistributing via eigrp 30, bgp 65037
10.234.241.16/28 is directly connected subent on the router and you are using eigrp and bgp on the router.
** Advertised by bgp 65037
subent 10.234.241.16/28 was advertised in BGP means it is redistibuted using "redisritbute connected" command under "router bgp 65037".
Thanks,

Thanks for posting the output of show ip protocol. In this output there is clear evidence that this subnet (or its interface) is included in EIGRP 30. In particular notice these lines:
Routing for Networks:
10.0.0.0
so there is a network statement for 10.0.0.0 and 10.234.241.22 is covered by the network statement and it is not made passive (only VLAN 30 is passive). So the address on VLAN 20 is an active EIGRP interface and the subnet is advertised by EIGRP.
It is harder to tell from the output about BGP. Pretty clearly BGP is advertising the network, but it is still ambiguous whether there is a BGP network statement for it or if it is being redistributed. I am thinking that there is a network statement for it under router bgp since it appears that BGP is redistributing static and eigrp routes, but that subnet is a connected subnet and not static or eigrp.
If you would post the config (or at least the router bgp part of the config) then we could determine for sure.

Hi Rick
Thanks for your share of explaination to the config. I get what your explaination is about. It would be diffcult to post the config as the config that i posted is only a small part of a whole enterprise network.
Thanks again for the sharing.
Thanks
