Please include vpp-dev alias on any questions about VPP, instead of unicast an individual only. Then whoever is familiar with the area you are asking about may respond. Does anyone know about the potential problem of switching between L2 and L3 modes on a bonded interface described in this email (I did change the email subject accordingly)? -John

I am very grateful for your help. And when I test the VLAN, maybe I find a bug that if I switch the mode of the Bonding interface to L2 and then switch back to L3，the bonding interface can not work as before. I have found the error code that is in the mode switch function of bonding device: when set the mode of bonding interface to l2, all the members of the bonding interface will be set to l2, but when set the bonding interface back, all the members do not recover to l3. At last I have another doubt that when I configure an IP address for an interface, then I ping the address from VPP, it’s failed, why?should I do other more settings? 2018年10月15日 星期一 +0800 22:20 发件人 John Lo (loj) <l...@cisco.com<mailto:l...@cisco.com>>: If there is a BVI in a BD with sub-interfaces in the same BD which get packets with VLAN tags, it is best to configure a tag-rewrite operation on the sub-interfaces to pop their VLAN tags. Then all packets are forwarded in BD without VLAN tags. The CLI is “set interface l2 tag-rewrite <sub-interface> pop 1” if the sub-interface has one VLAN tag. –John From: saint_sun 孙 <saint_...@aliyun.com<mailto:saint_...@aliyun.com>> Sent: Monday, October 15, 2018 2:42 AM To: John Lo (loj) <l...@cisco.com<mailto:l...@cisco.com>> Cc: vpp-dev@lists.fd.io<mailto:vpp-dev@lists.fd.io> Subject: Re: RE: [vpp-dev]vlan interface support? I am very grateful to you for your advice！ I have tested it，But there is something wrong. when I receive an arp or ICMP packet from a l2 subif that joins to bd 200 and encapsulates vlan 200，the reply packet that send from the subif does not have the vlan tag 200. Any more other configurations should I set？ 可用于iOS的myMail发送 2018年10月14日 星期日 +0800 04:58 发件人 l...@cisco.com<mailto:l...@cisco.com> <l...@cisco.com<mailto:l...@cisco.com>>: The equivalent of VLAN on a switch in VPP is a bridge domain or BD for short. One can put interfaces or VLAN sub-interfaces in a BD to form a L2 network among all interfaces in it. One can also create a loopback interface, put it in a BD as its BVI (Bridge Virtual Interface) and assign IP addresses to it. Then packet can be IP forwarded into a BD through its BVI. Following is the VPP CLI sequence to create a loopback (resulting in interface name loop0), put it in BD 13 as a BVI, and put an IP address on it: loopback create mac 1a:2b:3c:4d:5e:6f set interface l2 bridge loop0 13 bvi set interface state loop0 up set interface ip address loop0 6.0.0.250/16 Regards, John From: vpp-dev@lists.fd.io<mailto:vpp-dev@lists.fd.io> <vpp-dev@lists.fd.io<mailto:vpp-dev@lists.fd.io>> On Behalf Of saint_sun ? via Lists.Fd.Io Sent: Friday, October 12, 2018 3:52 AM To: vpp-dev@lists.fd.io<mailto:vpp-dev@lists.fd.io> Cc: vpp-dev@lists.fd.io<mailto:vpp-dev@lists.fd.io> Subject: [vpp-dev]vlan interface support? I have a question: Does vpp has the function like the configuration example: interface f0/1 switchport access vlan 10 Interface vlan 10 ip address 10.0.0.1 255.255.255.0 If vpp has the function, where can I find the command and the source code? Another question, does vpp support superVLAN? anyone who knows please tell me, appreciate for your reply very much!
