LDP on ex4200/3200 series..and 1RU LSR?

Thu, 21 Mar 2013 05:14:15 -0700 Post Comments

I had a couple over here, they seemed pretty good. I had L3VPN working and l2circuit but didn't try VPLS and I was not aware of the limitation.

Now, I am a little surprised about this lack of feature parity. It is supposed to be a Trio box, so shouldn't everything work?

All in all though the ACXs we tried were really good and we will be using them. It's better than all the SRX boxes I have out at the moment! (though they have worked really very well)

SCBE-MX XE XFP socket

Mon, 14 Jan 2013 05:01:11 -0800 Post Comments

Hey All,

Does anybody know what the XE XFP socket on the SCBE-MX for? I cannot find any documentation about it anywhere.

It's on the end of the card next to the clock interface.

Option dhcp-client-identifier ignored?

Tue, 27 Nov 2012 08:13:58 -0800 Post Comments

Folks,

I seem to have a small issue that I hope somebody can help with.

I am running Internet Systems Consortium DHCP Server 4.1-ESV-R4 on Linux and would like to assign a static IP address by dhcp-client-identifier.

This should be easy, yeah? It works on a Mikrotik DHCP server just fine.

Incoming requests have this option 61 present:

          Vendor-rfc1048 Extensions
            Magic Cookie 0x63825363
            DHCP-Message Option 53, length 1: Request
            Client-ID Option 61, length 17: "234514613700286^@"

The logging options I have enabled log it (using binary-to-ascii so its all in decimal):

Sep 20 03:50:40 xen-test dhcpd: client id 0:50:51:52:53:49:52:54:49:51:55:48:48:50:56:54:0

But the DHCP server ignores this option and just assigns a dynamic IP address from the range.

Requests are unicast relayed from a relay server.

The config is below, you'll see a whole load of hosts defined in every possible way (and I tried others besides) just out of desperation ;-)

Here is the server config:

ddns-update-style none;

option domain-name "example.org";
option domain-name-servers ns1.example.org, ns2.example.org;

default-lease-time 600;
max-lease-time 7200;

log-facility local7;
subnet 80.90.100.0 netmask 255.255.255.248 {
}

subnet 82.102.32.0 netmask 255.255.255.0 {

log (info, concat ( "client id ", binary-to-ascii(10,8,":", option dhcp-client-identifier)));
log (info, concat ( "address request ",  binary-to-ascii(10,8,".",  option dhcp-requested-address)));
log (info, concat ( "server id ",  binary-to-ascii(10,8,".", option dhcp-server-identifier)));

log (info, option dhcp-client-identifier);
log (info, option domain-name-servers);
log (info, option dhcp-message-type);

range 82.102.32.2 82.102.32.254;

option domain-name-servers 81.91.192.253;
