Group,
I am getting some conflicting info from the Doc-CD on the Passive-interface
command;
http://www.cisco.com/univercd
<http://www.cisco.com/univercd/cc/td/doc/product/software/ios124/124cr/hirp_
r/rte_eih.htm#wp1000250>
/cc/td/doc/product/software/ios124/124cr/hirp_r/rte_eih.htm#wp1000250
The link above states
Configuring the passive-interface command suppresses all incoming and
outgoing routing updates and hello messages. EIGRP neighbor adjacencies
cannot be established or maintained over an interface that is configured as
passive. "
Yet this link;
http://www.cisco.com/univercd
<http://www.cisco.com/univercd/cc/td/doc/product/software/ios124/124cr/hirp_
r/rte_pih.htm#wp1124419>
/cc/td/doc/product/software/ios124/124cr/hirp_r/rte_pih.htm#wp1124419
"Enhanced Interior Gateway Routing Protocol (EIGRP) is disabled on an
interface that is configured as passive although it advertises the route. "
Perhaps its me being silly, I always believed the first quote was correct
for EIGRP, and looking at Debugs on a network would make it true, but then I
decided to hub and "ethereal/wireshark" the packets outgoing and saw IP
protocol 88 being sent (EIGRP)
Does someone have an authoritative answer on this one?
Thanks
Graham
