Which EIGRP commands needed to propagate this static route?

[jmaxwellUSAF]

Hello.

In a 3900 router, which EIGRP commands are needed to propagate the below static route?

(Does EIGRP need a new network statement, or a redistribute statement? May you please list the needed config statement(s)?)

#ip route 10.1.128.0  255.255.240.0  172.16.0.5

>>UPDATE<< This will be performed in ASA 5525 and 1120.  I DO NOT need a static route, I only need to insert the route into EIGRP. (I'm sorry for the confusion.)

Thank you.

depends on where you looking to redistribute - but in general you can do as below :

redistribute static metric [bandwidth] [delay] [reliability] [load] [MTU]

which platform router or ASA ??

https://www.cisco.com/c/en/us/support/docs/security/asa-5500-x-series-next-generation-firewalls/91264-eigrp.html
check this guide for eigrp in asa

ASA 5525, and also ASA 1120.

I will now read your linked literature.

I expect the needed config input is simple, but I have little experience implementing EIGRP.

My updated understanding is that I DO NOT need a static route, I only need to insert the route into EIGRP.

Router-ASA 
the static route in Router 
so you need to 
redistribute the static into EIGRP in Router 

https://www.cisco.com/c/en/us/support/docs/ip/enhanced-interior-gateway-routing-protocol-eigrp/8606-redist.html#anc17

and for ASA I share good link for EIGRP in ASA.

Thank you for these informative links. I appreciate it.

You are so so welcome.

The link states...

interface GigabitEthernet0/0
description outside interface connected to the Internet
nameif outside
security-level 0
ip address 198.51.100.120 255.255.255.0

This is the static default gateway configuration

route outside 0.0.0.0 0.0.0.0 198.51.100.1 1

___

does "outside" refer to nameif "outside"?

According to the link example, shouldn't the static

default-gateway IP address be 198.51.100.120 ?

Thank you.

does "outside" refer to nameif "outside"? Yes it same nameif 

According to the link example, shouldn't the static

default-gateway

IP address be 198.51.100.12x? if P2P then it should 198.51.100.12x,  but if it Broadcast domain (ASA and other L3 device connect to one SW or more have same VLAN) then it can be any IP wihtin the range of VLAN subnet.

"According to the link example, shouldn't the static

This does not make sense to me. If there are 3 workstations in vlan77-- 10.0.0.1, 10.0.0.2, 10.0.0.3, and the

default gateway

is nameif outside 10.0.0.99. Then it seems to me that ONLY...

 #route outside 0.0.0.0 0.0.0.0 10.0.0.99

1 will work.

What do you say?

[MHM Cisco World]

First I correct previous comment, 
second, the route in FW must end with

next-hop

not IP of OUT interface. 
if you have 
ASA with OUT IP 10.0.0.99 
you can config the default to be 

route OUT 0.0.0.0 0.0.0.0 10.0.0.x <<- 10.0.0.x next-hop

A-if P2P 

ASA(10.0.0.99)-Router(10.0.0.100)

then it should 10.0.0.100

B- but if it Broadcast domain (ASA and other L3 device connect to one SW or more have same VLAN) then it can be any IP wihtin the range of VLAN subnet.

ASA(10.0.0.99)-SW-Router(10.0.0.51)
ASA(10.0.0.99)-SW-Router(10.0.0.52)
ASA(10.0.0.99)-SW-Router(10.0.0.100)

it can be 10.0.0.51 or 10.0.0.52 or 10.0.0.100

Hello,

It depends on how you want to advertise the network. Either the network command or the redistribute static command will work. A couple of caveats though.

Using the network command will advertise the route as an EIGRP internal route with an AD of 90.

Using the redistribute static command it will advertise the route as external with an AD of 170 (make sure you include the metrics in the same line of this command since EIGRP will advertise an infinite metric by default and it wont propagate). If you use this you have a bit more granular control as you can attach

route-map

to this and modify the attributes. You can also just include the one static route you want instead of every static route on the device. You can also apply the metrics within the static route.

Depending on how you want the route to show up in your network is the one you should choose. 

Hope that helps
