902 CHAPTER 57: IS-IS CONFIGURATIONConfiguring DynamicHost Name MappingFollow these steps to configure the dynamic host name mapping:n The local host name on the local IS overwrites the remote host name on theremote IS.Configuring IS-ISAuthenticationFor area authentication, the area authentication password is encapsulated into theLevel-1 LSP, CSNP, and PSNP packets. On area authentication enabled routers inthe same area, the authentication mode and password must be same.For routing domain authentication, the domain authentication password isencapsulated into the Level-2 LSP, CSNP, and PSNP packets. The domainauthentication enabled Level-2 routers in the backbone must adopt the sameauthentication mode and share the same password.Configure the SPF calculationintervalstimer spf maximum-interval[ minimum-interval[ incremental-interval ] ]OptionalThe default SPF calculationinterval is 10 seconds.Specify the SPF calculationdurationspf-slice-size duration-time Optional10 milliseconds by defaultTo do...
