ros设置单网卡拨多ADSL 使用vrrp 有些版本有问题，使用5.2破解版本测试成功。
1.创建100个vrrp,并绑定到wan口下
for i from 1 to 100 do={/interface vrrp add comment=("RP".$i) interface=wan interval=1 name=("vrrp".$i) vrid=$i}
2.修改vrrp 协议
for i from 1 to 100 do={/interface vrrp set v3-protocol=ipv6 numbers=("vrrp".$i)}
3.创建pppoe,（这里需要注意你的adsl 用户和密码），并绑定到对应的vrrp
for i from 1 to 100 do={/interface pppoe-client add add-default-route=yes allow=pap,chap comment=($i) interface=("vrrp".$i) max-mtu=1480 name=("pppoe-out".$i) user=$i password=$i }
设置pppoe 的为取消默认路由
for i from 0 to 99 do={/interface pppoe-client set numbers=$i add-default-route=no }
设置PCC负载均衡(原来的PPPOE需要取消默认路由，后边收到设置路由)
1.设置NAT
for i from 1 to 100 do={/ip firewall nat add chain=srcnat action=masquerade out-interface=("pppoe-out".$i) comment=("pppoe".$i)}
2.设置input
for i from 1 to 100 do={/ip firewall mangle add chain=input action=mark-connection new-connection-mark=("pppoe-out".$i."_conn") passthrough=yes in-interface=("pppoe-out".$i) comment=("input".$i)}
3.设置output
for i from 1 to 100 do={/ip firewall mangle add chain=output action=mark-routing new-routing-mark=("to_pppoe_out".$i) passthrough=yes connection-mark=("pppoe-out".$i."_conn") comment=("output".$i)}
4.设置连接标记
for i from 6 to 100 do={/ip firewall mangle add chain=prerouting action=mark-connection new-connection-mark=("pppoe-out".$i."_conn") passthrough=yes src-address=10.0.0.0/8 dst-address-type=!local in-interface=ether1-lan per-connection-classifier=("both-addresses:100/".$i-1) comment=("pcc".$i)}
5.设置路由标记
for i from 6 to 100 do={/ip firewall mangle add chain=prerouting action=mark-routing new-routing-mark=("to_pppoe_out".$i) passthrough=yes src-address=10.0.0.0/8 in-interface=ether1-lan connection-mark=("pppoe-out".$i."_conn") comment=("pcc".$i)}
6.手动设置路由
for i from 6 to 100 do={/ip route add comment=$i disabled=no distance=1 dst-address="0.0.0.0/0" gateway=("pppoe-out".$i) routing-mark=("to_pppoe_out".$i) check-gateway=("ping")}
7.设置路由ping 监控
for i from 8 to 100 do={/ip route add check-gateway="ping" comment=("pppoe-out".$i) disabled=no distance="10" dst-address="0.0.0.0/0" gateway=("pppoe-out".$i)}
