From 39e27b840e5ddc2087c0b20cfcf379745b3baa79 Mon Sep 17 00:00:00 2001 From: zhou-run <166502045+zhou-run@users.noreply.github.com> Date: Tue, 21 May 2024 17:19:44 +0800 Subject: [PATCH] isisd: When the metric-type is configured as "wide", the IS-IS generates incorrect metric values for IPv4 directly connected routes. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The IPv4 directly connected route prefix exists in both the root LSP and the root's neighbor LSP: 1. When generating vertices for directly connected route prefixes with a metric of 0 based on the root LSP, the isis_spf_preload_tent_ip_reach_cb function only generates vertices of type VTYPE_IPREACH_INTERNAL without distinguishing between area->oldmetric and area->newmetric. 2. When generating vertices for the directly connected route prefix based on the neighbor LSP, the isis_spf_process_lsp function will generate vertices of type VTYPE_IPREACH_INTERNAL and VTYPE_IPREACH_TE based on area->oldmetric and area->newmetric, where the vertex metric is the sum of the metric from the root IS to the neighbor IS and from the neighbor IS to the root IS, respectively. If area->newmetric=1, the same directly connected route prefix will have both VTYPE_IPREACH_INTERNAL vertices with a metric of 0 and VTYPE_IPREACH_TE vertices with a non-zero metric. During route generation, the isis_spf_loop function will prioritize selecting VTYPE_IPREACH_TE vertices, leading to incorrect metrics for the directly connected routes.
