I started two containers on one machine, but I can't ping between the two containers. The use environment is as follows:

root@loongson:~# cat /etc/os-release 
PRETTY_NAME="Debian GNU/Linux bookworm/sid"
NAME="Debian GNU/Linux"
VERSION_CODENAME=bookworm
ID=debian
HOME_URL="https://www.debian.org/"

Linux loongson 6.0.0-5-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.0.10-1 (2022-11-26) x86_64 GNU/Linux

Start the weave service:

weave launch
eval $(weave env)
weave expose
docker run -itd --name=test1 debian:10
docker run -itd --name=test2 debian:10

root@loongson:~# weave ps

root@loongson:~# weave version
weave script unreleased
weave git-34de0b10a69c

tes1 ping test2:

Use tcmp to capture packets and find that arp is normal, but there is no response to ICMP packets:
