Default route learned from "default information originate"?

[jmaxwellUSAF]

Gateway of last resort is 1.1.1.1 to network 0.0.0.0
D*EX 0.0.0.0 0.0.0.0 [170/51712] via 1.1.1.1, 1d01h, Outside
S 0.0.0.0 0.0.0.0 [255/0] via 172.16.1.1, Inside tunneled

Is it probable that that this router learned the D*EX route from a different router configured with "default information originate"?

Thank you.

As i saw other post you need to give more information about environment - what device model, what protocol you running, how is your network

as per your output concern  ( as we see other post more you looking at ASA since we see outside and inside interface there- as example)

D - EIGRP

*  - Candidate Default (since output show no other router there)

EX - stands to EIGRP external - which mean this is learning from different

that is Default

Yes it receive default route from EIGRP neighbor.

Hello,

As mentioned before we need more info. on your network. A couple things to note:

Default information originate is OSPF. A default route can be learned MANY ways.

The snippet you provided does not indicate one way or another how it learned the default route except its EIGRP external route....however you can put a static route on that same router of 0.0.0.0 0.0.0.0 1.1.1.1 255 and go into the EIGRP process and do a "redistribute static" and it would show up in the routing table  like that...in fact that may be what happened.

Can you provide the EIGRP configuration information (or better yet the entire running config on that devcie) in a text document and attach on here.

Hope that helps

Thank you folks. This question is a detail in a bigger troubleshoot. I am satisfied with the community info. Thank you!

can I ask you why you use tunnel keyword with default route ?

[jmaxwellUSAF]

cut/paste off production router-- I don't know why it is configured this way.

this not router this ASA I think and this tunnel with default use only for VPN .
