ASP.NET MVC 5 how to organize the correct routing when using pagination?

Question

Network administration

When writing a mini-forum, there was a problem with the generation of links during pagination.
I have 2 methods
The first one is responsible for displaying forums and forum topics

[Route("{forumName}", Name = "showForum", Order = 6)]
[Route("{forumName}/Page/{page}", Order = 5)]
[OutputCache(Duration = 30, VaryByParam = "forumName;page", Location = OutputCacheLocation.ServerAndClient)]
public async Task<ActionResult> ShowForum(string forumName, int page = 1)

Second, to display the theme

[HttpGet]
[RefreshDetectFilter]
[Block(VisibleBlock = false)]
[Route("{forum}/{topicName}", Name = "showTopic", Order = 8)]
[Route("{forum}/{topicName}/Page/{page}", Order = 7)]
[OutputCache(Duration = 30, VaryByParam = "topicName;page", Location = OutputCacheLocation.ServerAndClient)]
public async Task<ActionResult> ShowTopic(string forum, string topicName, int page = 1)

So, before I started using Url.RouteUrl , I had a problem with displaying a link to a topic when you go to the next page of the breakdown
For example:
When you were on the forum page
/Forums/Predloghenie/Page/2
The link to the topic was generated like this
/ Forums/Predloghenie/Testovayu_tema/Page/2 The
same applies when generating breadcrumb using the Html.MvcSiteMap().SiteMapPath() function from MvcSiteMapProvider, the link to the parent form is obtained like this:
/Forums/Kategoriyu_1/Page/2
For links to the topic, I found a solution , is to use Url.RouteUrl , but I don't know how to deal with breadcrumb. Is there a universal way to solve this problem?
