Description 
Use the set-overload command to set overload flag for the current router. 
Use the undo set-overload command to cancel the overload flag.  
By default, no overload flag is set. 
If a router is configured with the overload flag, the routes it calculates will be ignored by 
other routers in SPF calculation. (However the directly connected routes will not be 
ignored.) And other routers should not send this router the packets which should be 
forwarded by it. 
Example 
# Set overload flag on the current router. 
[Quidway-isis] set-overload

Syntax 
silent-interface silent-interface-type silent-interface-number 
undo silent-interface silent-interface-type silent-interface-number 
View 
IS-IS view 
Parameter 
silent-interface-type: Specifies the interface type. 
silent-interface-number: Specifies the interface number. 
Description 
Use the silent-interface command to disable a specified interface to transmit IS-IS 
packet. 
Use the undo silent-interface command to enable the interface to transmit IS-IS 
packet.  
By default, all the interface are allowed to transmit/receive IS-IS packets.  
The silent-interface command is only used to suppress the packets to be transmitted 
on the interface, but the routes of this interface will still be transmitted from other 
interfaces.  
Example 
# Prohibit the IS-IS packets to be transmitted via Interface Vlan-interface 3.
