RE: cannot ping loopback IP addresses [7:29345]
because both of your routers (loopbacks) by your subnet masking to the router are on the same LAN so when you try to ping they look at local interface. > -Original Message- > From: mindiani mindiani [SMTP:[EMAIL PROTECTED]] > Sent: Monday, 17 December 2001 7:02 am > To: [EMAIL PROTECTED] > Subject: cannot ping loopback IP addresses [7:29345] > > I have two routers connected to the same LAN but I cannot ping the > loopback > IP address of each other. from router1 I am not able to ping the loopback > of > router2 and vice-versa.

Re: cannot ping loopback IP addresses [7:29345]
How are your loopbacks learning about one another? You will want to redistribute the information about your loopbacks into a routing protocol or use static routes. Ideally, I would but the loopbacks into separate networks and then advertise those networks via the routing protocol of choice. I see the network 100.0.0.0 being advertised but I am not sure as to what it will default (classful or classless addressing). An output of sh ip route would be nice.

Re: cannot ping loopback IP addresses [7:29345]
You have both loopbacks on the same network. Try putting one of the loopbacks on a different network. -- -=Repy to group only... no personal=- ""mindiani mindiani"" wrote in message [EMAIL PROTECTED]">news:[EMAIL PROTECTED]... > I have two routers connected to the same LAN but I cannot ping the loopback > IP address of each other. from router1 I am not able to ping the loopback of > router2 and vice-versa.

cannot ping loopback IP addresses [7:29345]
I have two routers connected to the same LAN but I cannot ping the loopback IP address of each other. from router1 I am not able to ping the loopback of router2 and vice-versa. Why ?. Here is the sample config of the two routers. -- Router1: hostname router1 interface loopback0 ip address 100.0.1.1 255.255.255.0 ! interface Ethernet0 ip address 192.100.103.9 255.255.255.0 no ip-directed broadcast ! eigrp 1 network 192.100.103.0 network 100.0.0.0 no auto-summary - Router2: hostname router2 interface loopback0 ip address 100.0.1.6 255.255.255.0 ! interface Ethernet0 ip address 192.100.103.10 255.255.255.0 no ip-directed broadcast ! eigrp 1 network 192.100.103.0 network 100.0.0.0 no auto-summary _ Join the worlds largest e-mail service with MSN Hotmail. http://www.hotmail.com Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=29345&t=29345 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
