Loopback address isn't explicitly assigned to an interface. Assigning it resolves various issues. See http://forums.juniper.net/t5/Ethernet-Switching/NTP-Not-working/m-p/224757. set interfaces lo0.0 family inet address 127.0.0.1/32
As for NTP, and other stuff for the RE itself, I use same approach by explicitly putting 127.0.0.1/32 in the prefix-list. I originally did it because not all of the apply-path lists had the underlying configuration, resulting in an empty prefix-list that matched anything. Now, almost any apply-path based prefix list will have the loopback address specified. set policy-options prefix-list MY-NTP_SERVERS 127.0.0.1/32 set policy-options prefix-list MY-NTP_SERVERS apply-path "system ntp server <*>" -Chad On Jan 14, 2014, at 7:04 AM, Olivier Benghozi wrote: > But due to another ridiculous way of implementing that, the Juniper KB > article suggests to also allow: > <router-loopback-address>; > and not only your favorite ntp servers... > > Because if you don't do it, you'll obtain some nice "Server Timeout" if you > want to issue a "show ntp status" or "show ntp associations". > So: > - Junos doesn't use 127.0.0.1 to locally communicate with ntpd > - In you filters you're obliged to manually authorize internal private IP > traffic used by the CLI and that doesn't even leave the RE > > Another fine design... > > > -- > Olivier > > > Le 14 janv. 2014 à 03:10, John Kristoff <j...@cymru.com> a écrit : > >> On Tue, 14 Jan 2014 12:38:12 +1100 >> Mark Tees <markt...@gmail.com> wrote: >> >>> Can we get detailed lo0 filters listed too please? >> >> Hi Mark, >> >> While I'll defer to Juniper for their recommendations, we've had this >> for some time (scroll down to the Juniper section): >> >> <http://www.team-cymru.org/ReadingRoom/Templates/secure-ntp-template.html> > > > _______________________________________________ > juniper-nsp mailing list juniper-nsp@puck.nether.net > https://puck.nether.net/mailman/listinfo/juniper-nsp > This message may contain confidential information and is intended for specific recipients unless explicitly noted otherwise.
