Abstract
A first routing bridge (RB) according to an example determines whether there is a nickname conflict between nicknames of the first RB and a second RB. If there is a nickname conflict, the first RB determines whether it is a lower priority RB and may modify its nickname if it is lower priority and based on a broadcast of link state packet from the second RB.
Claims12
A method for processing a nickname conflict in a TRILL network, comprising:
- receiving, by a first Routing Bridge (RB), a Link State Packet (LSP) from a second RB;
- determining, according to the received LSP, whether nicknames for the first RB and the second RB conflict;
- in response to determining that the nicknames conflict, determining whether the first RB is a lower priority RB than the second RB based on comparing information of the first RB with information determined from the LSP;
- broadcasting the LSP received from the second RB in response to determining the first RB is the lower priority RB;
- modifying the nickname of the first RB if the first RB receives another LSP from the second RB within a predefined period of time of receiving the LSP;
- and
- keeping the nickname of the first RB unchanged if the first RB does not receive another LSP from the second RB within the predefined period of time.

A first routing bridge (RB) to process a nickname conflict in a TRILL network, the RB comprising:
- a processor;
- and
- a memory storing machine readable instructions executable by the processor to:
- receive a Link State Packet (LSP) from a second RB;
- determine, according to the received LSP, whether nicknames for the first RB and the second RB conflict;
- in response to determining that the nicknames conflict, determine whether the first RB is a lower priority RB than the second RB based on comparing information of the first RB with information determined from the LSP;
- broadcast the LSP received from the second RB in response to determining the first RB is the lower priority RB;
- modify the nickname of the first RB if the first RB receives another LSP from the second RB within a predefined period of time of receiving the LSP;
- and
- keep the nickname of the first RB unchanged if the first RB does not receive another LSP from the second RB within the predefined period of time.
