Hi
My understanding as following, if i am wrong correct me.
1. lb plugin work in DSR mode, lb will not change dst ip address of incoming
packet , and i read the code,lb will use selected as ip address as gre outer
dst ip address.
2. client communicate to vip not use gre tunnel, vip communicate to as by gre
tunnel.
I am new to vpp and lb, If you can write a more detailed doc about how to set
topology,that would be more appericiate.

Hi Pierre
Thanks for your reply.
For example, i have one interface called Ethernet0/1/0 which is managed by
vpp.
then, we create two gre tunnel interfaces, gre0 and gre1.
e.g.
Ethernet0/1/0 has two ip addresses 10.0.1.1/24 and 10.0.2.1/24.
There are two hosts connect to Ethernet0/1/0, and its ip address is
10.0.1.2/24 and 10.0.2.2/24
gre0: remote ip address 10.0.1.2, local ip address 10.0.1.1
gre1: remote ip address 10.0.2.2, local ip address 10.0.2.2
ip address of gre0: 192.168.1.1/24
ip address of gre1: 192.168.2.1/24
LB configuration:
lb conf 10.0.2.1
lb vip 192.168.3.1
lb as 192.168.3.2, 192.168.3.3, 192.168.3.4
There question:
1. which interface the vip should configure to?
The VIP is usually configured as a loopback address on the hosts.
2. Can vip and as belong to two different subnet?
Sure. VIP stands for virtual address. It is not a topological address.
Multiple hosts avec the same VIP (as loopback addresses).
3. Is the above configuration right?
I wouldn't call the above "a configuration". I mean, the syntax seams incorrect.
Plus the GRE tunnels are only configured on the hosts, so if I understood
correctly, you got the local/remote backward.
Cheers,

Yes, I read the doc and maglev, one question , do we need to create two
interfaces? One is for VIP , the other is for communicating as?
No. It's all encap/decap. So it should work with a single interface.

Hello,
Are you familiar with MagLev ?
Did you take a look at
