Yersinia 介绍
Yersinia 实现了很多协议堆栈，包括: Spanning Tree (STP), Cisco Discovery (CDP), Dynamic
Host Configuration (DHCP), Hot Standby Router (HSRP), Dynamic Trunking (DTP),
802.1q, Inter-Switch Link Protocol (ISL), and VLAN Trunking (VTP).
It helps the pen-tester in different tasks, such as becoming the root role in
the Spanning Tree, creating virtual CDP neighbors, setting up rogue DHCP
servers, becoming the active router in a HSRP scenario, enabling trunk,
performing ARP spoofing over VLAN hopping, adding or deleting VLANs (via VTP),
and more.
