Layer 2 feature on srx
hello expert,
i use two srx210h to test some Layer 2 networking features on MX Series routers. the topo is very simple
PC1---SRX1----SRX2----PC2. the link in srx1---srx2 is set to trunk mode. PC1 and PC2 is belong to vlan 100. PC1 can't ping PC2.


interfaces {
ge-0/0/1 {
description TO-SRX2;
vlan-tagging;
unit 0 {
family bridge {
interface-mode trunk;
vlan-id-list [ 100 200 ];
}
}
}
fe-0/0/4 {
unit 0 {
family bridge {
interface-mode access;
vlan-id 100;
}
}
}
irb {
unit 100 {
description "GW For VLAN 100";
family inet {
address 100.1.1.254/24;
}
}
unit 200 {
description "GW For VLAN 200";
family inet {
address 200.1.1.254/24;
}
}
}
}
security {
forwarding-options {
family {
mpls {
mode packet-based;
}
}
}
}
bridge-domains {
vlan_100 {
vlan-id 100;
routing-interface irb.100;
}
vlan_200 {
vlan-id 200;
routing-interface irb.200;
}
}

Re: Layer 2 feature on srx [In reply to]
Are you missing zones/policies since it is SRX?

Re: Layer 2 feature on srx [In reply to]
What software are you running on your SRX's?

The only reason I ask is that I am running 10.4R4.5 on an SRX100, and
this is how I do my VLANs (SRX is in flow mode, but does that really
matter to L2??):

interfaces {
fe-0/0/1 {
description "** Trunk to esxi1";
unit 0 {
family ethernet-switching {
port-mode trunk;
vlan {
members all;
}
native-vlan-id 1;
}
}
}
fe-0/0/4 {
description "** Console server";
unit 0 {
family ethernet-switching {
vlan {
members VLAN11-MGMT;
}
}
}
}
vlan {
unit 10 {
family inet {
address 172.25.144.65/26;
}
family inet6 {
address 2001:xxxx:yyyy:1::/64 {
eui-64;
}
}
}
unit 11 {
family inet {
address 172.25.144.17/28;
}
}
}
}
vlans {
VLAN10-LAN {
vlan-id 10;
l3-interface vlan.10;
}
VLAN11-MGMT {
vlan-id 11;
l3-interface vlan.11;
}
}

The primary difference seems to be that I use "vlans" instead of
"bridge-domains" at the bottom, and the "vlan" interface instead of
"irb".

Ive also successfully trunked VLANs to/from a HP switch using this
configuration.

Re: Layer 2 feature on srx [In reply to]
Off the cuff..Looks to me like you're missing your bridge domain-type.
Sadly this doesn't produce any kind of errors when you attempt to
commit.

set bridge-domains <name> domain-type bridge.

Additionally I noticed you're using two different vlans. As long as
traffic is flowing across a single vlan you'll be fine. If they need
to go from vlan 100 to 200 you'll need to do a vlan rewrite.

Hope this helps,

Your config only shows packet-mode for "family mpls". IPv4 will still be
flow mode.

Re: Layer 2 feature on srx [In reply to]
In the context of packet-mode, the family mpls is analogous to inet. This
is correct.

I suggest that the OP use "set vlan <name>" instead of "set bridge-domain
<name>" Also use "set interfaces vlan" instead of "set interfaces irb"

I'm not even sure why the SRX accepted this configuration.

Thank you,

The MX-style L2 commands are supported on SRX (branch as well and yes) and
looks like this is for transparent flow mode. With some limitations though.
Say you can't enable flexible-ethernet-services on FE interfaces, only on
GE. Enabling flexible-vlan-taggin gives you the following warning: "Only
compatible with vpls vlan encapsulations" (I haven't ever seen anything
like this on MX), etc.

So as far as I understand

MX-style L2 config:

— for transparent flow mode,
— IRB interfaces are for management traffic only,
— switching performed in software for branch and I wonder where on Hi-End,
— have no idea what happens to it in packet-mode.

EX-style L2 config:

— for general switching,
— performed by broadcom chips,
— have consequent limitation applied to ports, between which traffic can be
switched (same PIM),
— RVI interfaces can really route traffic (software based both in packet
and flow modes).

More details:
http://www.juniper.net/techpubs/en_US/junos11.4/information-products/topic-collections/security/software-all/layer-2/index.html

Would be pleasant If someone can sort out points I marked with "I'm not
sure/have no idea". Or, if I'm totally wrong somewhere, please tell me.

OP wanted to use the IRB ints as next hop for their respective
networks. This is apparently not supported on the SRX platform in
transparent mode:
"In this release, the IRB interface on the SRX Series device does not
support traffic forwarding or routing. In transparent mode, packets
arriving on a Layer 2 interface that are destined for the device’s MAC
address are classified as Layer 3 traffic while packets that are not
destined for the device’s MAC address are classified as Layer 2
traffic. Packets destined for the device’s MAC address are sent to the
IRB interface. Packets from the device’s routing engine are sent out
the IRB interface."

So in transparent / IRB mode the IRB int can only be used as a
management interface.

OP needs to do is MX testing using an MX device.

Yeah, I mentioned this as well. In my post I just wanted to explain why
these (MX-style L2) commands were successfully committed by SRX (which
is really not obvious and I even think, someone who decided to reuse
this part config for this purpose on SRX needed to think twice or at
least document it more clearly. This is not the first time I see such a
confusion).

IICR, by now they can't even terminate IPSec on IRB. An interesting
question here is whether they are going to make IRBs to be real L3
ifaces. What a mess it would be :)
