Re: The same network and id vlan in different contex in the same
Sharing Vlans is possible in routed mode.
Its not possible when ACE is operating in Bridge mode.
You need to use unique IP addresses in each context for shared vlans.
Also make sure to use " shared-vlan-hostid " command.
When contexts share a VLAN, the ACE assigns a different MAC address to the VLAN on each context. The MAC addresses reserved for shared VLANs are 0x001243dc6b00 to 0x001243dcaaff, inclusive. All ACE modules derive these addresses from a global pool of 16k MAC addresses. This pool is divided into 16 banks, each containing 1,024 addresses. An ACE supports only 1,024 shared VLANs, and would use only one bank of MAC addresses out of the pool.
By default, the bank of MAC addresses that the ACE uses is randomly selected at boot time. However, if you configure two ACE modules in the same Layer 2 network and they are using shared VLANs, the ACEs may select the same address bank and use the same MAC addresses. To avoid this conflict, you need to configure the bank that the ACEs will use. "
