Hello everyone.
I`m trying to set up mc-lag in my lab environment which looks like this:
MX104
/ ae0 \
/ \
/ ae1(mc-lag) \
QFX1 -------------- QFX2
ae0
So i`ve got mc-lag between MX104 and 2 QFX 5110 switches.
MX104:
description "To QFX MC-LAG";
flexible-vlan-tagging;
mtu 9000;
encapsulation flexible-ethernet-services;
aggregated-ether-options {
minimum-links 1;
link-speed 10g;
lacp {
active;
periodic fast;
}
}
unit 4000 {
vlan-id 4000;
}
On QFX-1:
ae0 which used for iccp:
mtu 9000;
aggregated-ether-options {
minimum-links 1;
link-speed 10g;
lacp {
active;
periodic fast;
}
}
unit 0 {
family ethernet-switching {
interface-mode trunk;
vlan {
members all;
}
}
}
ae1 - mc-lag interface
mtu 9000;
aggregated-ether-options {
lacp {
active;
periodic fast;
system-id 00:01:02:03:04:05;
admin-key 3;
}
mc-ae {
mc-ae-id 3;
chassis-id 0;
mode active-active;
status-control active;
init-delay-time 240;
}
}
unit 0 {
family ethernet-switching {
interface-mode trunk;
vlan {
members [ DC ICCP-4000 QFX-2_MX QFX-1_MX ];
}
}
}
Interface for ICCP:
show interfaces irb unit 4000
family inet {
address 10.1.2.1/30 {
arp 10.1.2.2 l2-interface ae0.0 mac f0:4b:3a:99:80:20;
}
}
on QFX-2
ae0
mtu 9000;
aggregated-ether-options {
minimum-links 1;
link-speed 10g;
lacp {
active;
periodic fast;
}
}
unit 0 {
family ethernet-switching {
interface-mode trunk;
vlan {
members all;
}
}
}
ae1:
mtu 9000;
aggregated-ether-options {
lacp {
active;
periodic fast;
system-id 00:01:02:03:04:05;
admin-key 3;
}
mc-ae {
mc-ae-id 3;
chassis-id 1;
mode active-active;
status-control standby;
init-delay-time 240;
}
}
unit 0 {
family ethernet-switching {
interface-mode trunk;
vlan {
members [ DC ICCP-4000 QFX-2_MX QFX-1_MX ];
}
}
}
Interface for ICCP:
show interfaces irb unit 4000
family inet {
address 10.1.2.2/30 {
arp 10.1.2.1 l2-interface ae0.0 mac f0:4b:3a:99:03:20;
}
}
everything works fine.
than i want to add l3-interfaces between QFX1-MX and QFX2-MX:
on MX104:
show interfaces ae0 | display inheritance | except #
description "To QFX MC-LAG";
flexible-vlan-tagging;
mtu 9000;
encapsulation flexible-ethernet-services;
aggregated-ether-options {
minimum-links 1;
link-speed 10g;
lacp {
active;
periodic fast;
}
}
unit 4000 {
vlan-id 4000;
}
unit 4001 {
description "To QFX-1 routing";
vlan-id 4001;
family inet {
address 10.1.1.9/30;
}
}
unit 4002 {
description "To QFX-2 routing";
vlan-id 4002;
family inet {
address 10.1.1.13/30;
}
}
On QFX-1:
show interfaces irb
unit 4000 {
family inet {
address 10.1.2.1/30 {
arp 10.1.2.2 l2-interface ae0.0 mac f0:4b:3a:99:80:20;
}
}
}
unit 4001 {
family inet {
address 10.1.1.10/30;
}
}
on QFX-2
show interfaces irb
unit 4000 {
family inet {
address 10.1.2.2/30 {
arp 10.1.2.1 l2-interface ae0.0 mac f0:4b:3a:99:03:20;
}
}
}
unit 4002 {
family inet {
address 10.1.1.14/30;
}
family iso;
family mpls;
}
And the problem that i can only ping from QFX-1 to MX ( 10.1.1.8/30 ) but can not ping from QFX-2 to MX ( 10.1.1.12/30)
when i`m shutting down QFX-1 i can ping 10.1.1.12/30
