Hi Experts, I have installed Gentoo on a Dell server and have configured vlans on it for one of the interfaces. My interface configuration looks like :-
enp4s0f1: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet6 fe80::20f:53ff:fe25:ef41 prefixlen 64 scopeid 0x20<link>
ether 00:0f:53:25:ef:41 txqueuelen 1000 (Ethernet)
RX packets 491116 bytes 36356615 (34.6 MiB)
RX errors 0 dropped 172 overruns 0 frame 0
TX packets 1513 bytes 101304 (98.9 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
device interrupt 44
enp4s0f1.3299: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 172.17.231.252 netmask 255.255.255.248 broadcast 172.17.231.255
inet6 fe80::20f:53ff:fe25:ef41 prefixlen 64 scopeid 0x20<link>
ether 00:0f:53:25:ef:41 txqueuelen 0 (Ethernet)
RX packets 82915 bytes 7198551 (6.8 MiB)
RX errors 0 dropped 297 overruns 0 frame 0
TX packets 1440 bytes 76816 (75.0 KiB)
TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0
I am joining a multicast group via this vlan interface enp4s0f1.3299 . When I do 'netstat -ang', I see a WEIRD thing.
enp4s0f0 1 224.0.0.1
enp4s0f1 1 224.0.0.1
enp4s0f1.3 1 224.0.27.58
enp4s0f1.3 1 224.0.0.1

enp4s0f1 1 ff01::1
enp4s0f1.3299 1 ff02::1:ff25:ef41
enp4s0f1.3299 1 ff02::1
enp4s0f1.3299 1 ff01::1
Instead of enp4s0f1.3299 interface joining the multicast group, I see interface enp4s0f1.3 joining it which does not even exist. I am not sure from where did this interface came.
Could you please help me with this ?
Appreciate all your help in advance. |
