Hello experts.
About the sub-interfaces on GigaEthernet interface.
I connect two Juniper back-to-back to make this test, and discard that the summit were the problem.
M5_A<=====>M7i_B
Test 1:
I configure both of them without sub-interfaces and without VLAN, the router's see each other.
Test 2:
I configure both router with sub-interfaces encapsulation dot1q(0x8100), the router's see each other.
Test 3
I configure both router with sub-interfaces encapsulation 802.1ad(0x88a8), the router's don't see each other.
M5_A (Version 8.3R1.5)
ge-0/2/0 {
description "===to M7i Test===";
flexible-vlan-tagging;
gigether-options {
ethernet-switch-profile {
tag-protocol-id 0x88a8;
}
}
unit 50 {
vlan-tags outer 0x88a8.50 inner 10;
family inet {
address 192.168.38.57/30;
}
}
}
M7i_B (Version 8.5R4.3)
interfaces {
ge-0/0/0 {
description "===to M5 Test ===";
flexible-vlan-tagging;
gigether-options {
ethernet-switch-profile {
tag-protocol-id 0x88a8;
}
}
unit 50 {
vlan-tags outer 0x88a8.50 inner 10;
family inet {
address 192.168.38.58/30;
}
}
}
Test 4
I configure both router with sub-interfaces encapsulation QinQ(0x9100), the router's don't see each other.
M5_A (Version 8.3R1.5)
ge-0/2/0 {
description "===to M7i Test===";
flexible-vlan-tagging;
gigether-options {
ethernet-switch-profile {
tag-protocol-id 0x9100;
}
}
unit 50 {
vlan-tags outer 0x9100.50 inner 10;
family inet {
address 192.168.38.57/30;
}
}
}
M7i_B (Version 8.5R4.3)
interfaces {
ge-0/0/0 {
description "===to M5 Test ===";
flexible-vlan-tagging;
gigether-options {
ethernet-switch-profile {
tag-protocol-id 0x9100;
}
}
unit 50 {
vlan-tags outer 0x9100.50 inner 10;
family inet {
address 192.168.38.58/30;
}
}
}
In the two las test(3,4) I ran a ping to the IP 192.168.38.58 in the router M7i_B, this should response because is in the interface of this router. IMHO, but this one doesn't response.
Thaks for your help.
Best regards.
