IS-IS LSP fragments are identified by the LSP Number field in their LSP IDs. This field is 4 bits long.
Therefore, an IS-IS process can generate a maximum of 256 LSP fragments, which means only a limited amount of information can be carried. By adding additional system IDs, you can enable the IS-IS process to generate more LSP fragments.

QUESTION NO: 9
VLAN aggregation is configured on a switched network. Sub-VLAN 2 and Sub-VLAN 3 are added to Super- VLAN 10. To enable hosts in different sub-VLANs to communicate with each other, run the following command in the VLANIF 10 view corresponding to the Super-VLAN.
(Enter lowercase letters.)
VLAN aggregation is configured on a switched network. Sub-VLAN 2 and Sub-VLAN 3 are added to Super- VLAN 10. To enable hosts in different sub-VLANs to communicate with each other, run the following command in the VLANIF 10 view corresponding to the Super-VLAN.
(Enter lowercase letters.)
Correct Answer:
inter-sub-vlan-proxy enable
Explanation:
Understanding VLAN Aggregation (Super-VLAN and Sub-VLANs)
* VLAN aggregation allows multiple sub-VLANs to be grouped under a super-VLAN, reducing the number of VLANIF interfaces required for IP address configuration.
* Super-VLAN: A logical VLAN that does not forward Layer 2 traffic directly but is used for Layer 3 communication.
* Sub-VLANs: VLANs that exist within the Super-VLAN but cannot communicate with each other by default.
2## Why is the " inter-sub-vlan-proxy enable " Command Needed?
* By default, hosts in different sub-VLANs under the same super-VLAN cannot communicate with each other because sub-VLANs do not exchange MAC address information.
* The inter-sub-vlan-proxy enable command allows Layer 3 communication between sub-VLANs under the same super-VLAN by acting as a proxy for ARP requests and replies.
* This enables inter-sub-VLAN communication while still reducing the number of VLANIF interfaces required.
3## Command Syntax and Execution
* The correct command should be run under the VLANIF interface of the super-VLAN:
[Switch] interface vlanif 10
[Switch-Vlanif10] inter-sub-vlan-proxy enable
