与mininet的网络接口

Question

我正在模拟具有mininet和ipmininet库的IPv6网络。拓扑工作正常，但是当我运行拓扑时，不会创建网络接口。如果执行“ ifconfig”命令，则只会出现三个接口：“ enp4s0，wlp2s0和lo”，但是我还需要显示在拓扑中创建的路由器的接口。我该怎么解决？

拓扑代码是：

import argparse
import json
import os
from mininet.log import LEVELS, lg

import ipmininet
from ipmininet.cli import IPCLI
from ipmininet.ipnet import IPNet
from ipmininet.router.config.zebra import StaticRoute, Zebra
from ipmininet.router.config.base import RouterConfig
from ipmininet.iptopo import IPTopo

from mininet.log import lg

"""

This file contains a simple topology with three routers and three hosts 


  a ---- r1  ---- r2 ---- r3  ----  b

                   c
