How will that help ? You aren't creating the EBGP session from the
firewall to the ISP. The firewall cant run BGP (if it's PIX or ASA)

Why don't you create an OSPF relationship between the firewall and
router. Then create a "dummy" network address/host on the firewall and
advertise that into OSPF.

Then redistribute that into BGP on the router. Create your
advertise-map/no-exist map etc, so when the firewall goes down and that
network/host disappears then so does your advertisement of 1.1.1.0/24

I have one idea , Create a another EBGP between Switch and ISP and
advertise (1..1.1.24 ) , When firewall is down EBGP will go down and
netwrol will withdrawn.

Please correct me if I wrong..

Hi All,

I have a customer scenario where

ISP 2.2.2.1----2.2.2.2 router1.1.1.1/24 -------Switch -----------
1.1.1.2/24FW------LAN

ISP and router are running BGP. Now I want to advertise the 1.1.1.0/24
when
FW is up if FW is down I dont want to advertise this subnet. I have
redundancy so will use redundant media and firewall . my querriery is
how
not to advertise in BGP 1.1.1.0/24when my FW is down.
