OSPF with passive interface [7:71395]
If the interface configured as passive under OSPF routing protocol, will there be any neighbor relationship establish on that interface ? (assume OSPF is on both router interfaces connected with a T1 circuit) Thank you Shibu Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=71395&t=71395 -- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
Loopback connection on Switch with STP [7:71394]
May find it very simple but could not find an accurate answer... Did not have a lab switch to try it out... If i make a loopback (cross cable) connectivity between 2 ports within the switch. And having the STP enabled on the switch, what would be the status for the ports... I thought it is "one will be blocking and one will be forwarding". Is that a right statement ? What if the bridge will act as root bridge (according to theory, ports on the root bridge should be on forward mode) ? But then the loop would be there... Your advice is appreciated.

ICMP access list keywords for traceroute unix application [7:71662]
Hi Can somebody let me know what exact keyword (not icmp type number) should be used to enable the incoming access-list for trace route unix application to work fine... I know UDP should be allowed for outgoing and ICMP should be allowed for the incoming... Looking for the incoming side icmp access list "key words" For looking these keywords I did the following on the router, But its a lot and do not know which one required for unix traceroute. access-list 101 permit icmp any any ?
