Config Baggers

Marcel — Tue, 16 Oct 2007 20:25:13 +0000

People stop bugging me for Juniper configs. I’m not your personal create my first Juniper
config engine. Everything on my blog you may / can use if you like. I’m not going
to write your configs. Really how hard can it be to design / write your own configs.

So please stop asking me for complete configs !!!! Get a J Course or Google a bit

JUNOS software Upgrade Redundant Routing Engines

Marcel — Fri, 31 Aug 2007 09:57:52 +0000

To upgrade Junos on a M-series Juniper with redundant routing engines you do it the following way.

 Log in to the master Routing Engine.

 Enter the JUNOS software configuration mode:

	{master}

	marcel@re0.lab2> configure

 Disable Routing Engine redundancy.

	{master} [edit]

	marcel@re0.lab2# delete chassis redundancy

 Save the configuration change on both Routing Engines.

	{master} [edit]

	marcel@re0.lab2# commit synchronize and-quit

 Log in to the backup Routing Engine.

{master}
marcel@re0.lab2> request routing-engine login other routing-engine

	{backup}

	marcel@re1.lab2> request system software add

	/var/home/marcel/jinstall-8.xxx.x-domestic-signed.tgz reboot

 Switchover to the other Routing Engine to change the role.

{backup}
marcel@re1.lab2> quit

       {master}
       marcel@re0.lab2> request chassis routing-engine master switch

       marcel@re0.lab2>

 Install the new software version on the Backup Routing Engine.

	{backup}

	marcel@re0.lab2> request system software add

	/var/home/marcel/jinstall-8.xxx.x-domestic-signed.tgz reboot

 Enable Routing Engine Redundancy again

	{master}

	marcel@re1.lab2> configure

	[edit]

	marcel@re1.lab2# rollback 1

 Save the configuration change on both Routing Engines

	[edit]	marcel@re1.lab2> commit synchronize and-quit

 If you are satisfied that the new software is running smoothly

{master}

	marcel@re1.lab2> request routing-engine login other routing-engine

	{backup}

	marcel@re0.lab2> request system snapshot

	{backup}

	marcel@re0.lab2> quit

Juniper Aggregated Links

Marcel — Tue, 28 Aug 2007 04:38:04 +0000

Something about aggregated links on Juniper M series.

It is not hard to config aggregated links.

[edit]
marcel@lab2# show chassis
aggregated-devices {
    ethernet {
        device-count 2;
    }
}
---
[edit]
marcel@lab2# show interfaces ge-1/0/0
gigether-options {
    802.3ad ae0;
}

[edit]
marcel@lab2# show interfaces ge-1/1/0
gigether-options {
   802.3ad ae0;
}

[edit]
marcel@lab2# show interfaces ae0
description "AE0 towards lab-1";
unit 0 {
   family inet {
       filter {
           input AMSIX-in;
           output AMSIX-out;
       }
       address 10.10.4.2/30;
   }
   family inet6 {
       address 2001:0960:1300:1144::1/64;
   }
}

It is also possible to use load balancing per packet.
