lo0.0 interface is to be configured under "set interfaces lo0 blah". Because you really don't want a changing lo0 IP if there's a switchover. Usually in re0/1 groups for MX (or member0/1 for Virtual Chassis EX switches, or member0/1-re0/1 for Virtual Chassis MX) you define a hostname mentioning re0/re1, and some OOB interface stuff (fpx0, if you use it).
So, again a poorly written documentation (written to illustrate one and only one function in fact, not to have a globally working config). By the way you'll also benefit from reading doc about non-stop-routing: http://www.juniper.net/documentation/en_US/junos14.2/topics/task/configuration/nsr-configuring.html <http://www.juniper.net/documentation/en_US/junos14.2/topics/task/configuration/nsr-configuring.html> This is what makes dual-RE something really useful, after all. > Le 9 mai 2016 à 14:37, v <vekt...@gmx.net> a écrit : > > Thank you! > > However, if I understand correctly that configuration snippet is from the > fxp0 interface.
