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)}
