Hi David, Donald,
I check the behaviour of latest FRR code. For me, it working as expected. Setting at least one of the TE parameters under the link-params statement automatically set enable under the link-params node. "no metric" command doesn't deactivate the link-params: "no enable" do the job.
Controlling LP flags with "link-params" / "no
link-params" is not feasible as link-params is a node in the CLI.
BTW, there is some redundancy between LP_TE and LP_TE_METRIC flags. LP_TE is not necessary to determine is link-params is set or not. My original intention was to control LP by testing if "lp_status" is equal to 0 or not. This is the role of IS_LINK_PARAM_SET macro.
Patch follow to rationalize LP flags by removing LP_TE and use only LP_TE_METRIC.
Regards
Olivier
Applied this version of the patch. Olivier - the previous and current situation was/is that doing "no metric" makes the entire "link-params" block go away in show running-config. Is that intended? Wouldn't it make more sense to control the LP_TE flag by the "link-params" / "no link-params" statement itself? (If you want to change things around, please send a patch :) -David On Thu, Dec 01, 2016 at 10:49:22AM -0500, Donald Sharp wrote:When link-params is configured it auto starts displaying 6000-02# conf t dell-s6000-02(config)# int swp1 dell-s6000-02(config-if)# link-params dell-s6000-02(config-link-params)# admin-grp 0x12345678 dell-s6000-02(config-link-params)# end dell-s6000-02# show run interface swp1 link-params enable metric 0 <----Remove the bw lines max-bw 1.25e+06 max-rsv-bw 1.25e+06 unrsv-bw 0 1.25e+06 unrsv-bw 1 1.25e+06 unrsv-bw 2 1.25e+06 unrsv-bw 3 1.25e+06 unrsv-bw 4 1.25e+06 unrsv-bw 5 1.25e+06 unrsv-bw 6 1.25e+06 unrsv-bw 7 1.25e+06 admin-grp 305419896 exit-link-params !
