Dear all,
I try to setup a VLAN in a VE and enable the VE to communicate with other PCs/servers in same VLAN but in outside world.
So the network configuration should look like this:
+--WORLD--+ +--MY_PC--+ +---VE---+
|VID=11's |---|eth0 | | |
|PCs | |veth101.0|---|eth0 |
|servers | +---------+ |eth0.11 |
+---------+ +--------+
I have the following configurations:
VE's ip route:
10.0.0.0/24 dev eth0.11 proto kernel scope link src 10.0.0.101
default dev eth0 scope link
MY_PC's ip route:
192.168.0.101 dev veth101.0 scope link
192.168.19.0/24 dev eth0 proto kernel scope link src 192.168.19.136
default via 192.168.19.2 dev eth0
However, routing of the tagged packets stops at MY_PC's veth101.0.
Folllowing is the tcpdump log on MY_PC, I monitor both MY_PC's veth101.0 and eth0:
Tagged packets do arrive MY_PC's veth101.0

Tagged packets never arrive MY_PC's eth0 and passed to WORLD.
/usr/sbin/tcpdump -ne -i eth0 -xx not port 22
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes
According to MY_PC's routing table, I don't set any rule for the packets to destination 10.0.0.0/24,
so they should be routed to the next stop by default gateway (MY_PC's eth0).
Please advise.
