Hi,
I have a QFX5120-32C switch running 18.4R2-S5.4, the switch acts as bridge sitting in between two MX-routers where IS-IS is running over the connections, the switch suddenly seems to be consuming IIH from the router to its RE
QFX5120-32C> monitor traffic interface et-0/0/11
<snip>
Listening on et-0/0/11, capture size 96 bytes
02:42:27.628112 In IS-IS, p2p IIH, src-id 0101.0100.1010, length 5702:42:30.890840 In ES-IS, ISH, length 43
QFX5120-32C> show configuration interfaces et-0/0/11
description "facing ISIS router 1";
unit 0 {
family ethernet-switching {
interface-mode access;
vlan {
members vlan-100;
}
}
is this the right behavior of a switch? why would a switch RE needs to know anything about an IS-IS hello packets? how do I know wether the switch actually sent the original IIH copy to the other interface to egress out of the switch? (I won't be able to see this IIH frame going out with "monitor traffic interface" unless I do port mirroring on the other interface which I can not do). any clue?
