IX2105でDS-Lite
てくろぐ: IIJmioひかりの混雑の理由とバイパス手段(IPoE・DS-Lite対応)
動かしてみたら確かにサラマンダーPPPoEより、ずっとはやい!!
IXでの設定例があんまり見つからなかったので、ペタリ

IXでのDS-Lite設定の肝はこの辺
ip route default Tunnel0.0
ipv4のルーティングはトンネルをデフォゲ
no bridge 1 bridge ip interface GigaEthernet0.0 bridge-group 1 interface GigaEthernet1.0 bridge-group 1
ipv4のブリッジを禁止(GE0とGE1でipv6だけブリッジする)
tunnel mode 4-over-6 tunnel destination 2404:8e00::feed:100
