Multiple pattern in single symfony routing

Question

How to make multiple pattern in single Symfony routing?

Normally we have a routing as

blog:
    pattern:   /
    defaults:  { _controller: AcmeBlogB

When using YAML routes you can also use the node anchors expression syntax to reference an existing route definition.

& specifies the first occurrence of an anchor, * specifies the anchor to reference, << tells the Symfony yaml parser to merge the specified node.

blog: &blog
  path: /
  defaults:  { _controller: AcmeBlogBundle:Blog:index, page: 1 }

blog_index:
  <<: *blog
  path: /index

blog_page:
  <<: *blog
  path: /blog

Alternatively you can use anchors on a route attribute value.

blog:
  path: /
  defaults: &blog_defaults
    _controller: AcmeBlogBundle:Blog:index
    page: 1

blog_index:
  path: /index
  defaults: *blog_defaults

blog_page:
  path: /blog
  defaults: *blog_defaults

However to prevent poor SEO due to duplicate content, it is recommended to use a redirect instead.

blog:
  path: /
  defaults: { _controller: AcmeBlogBundle:Blog:index, page: 1 }

blog_index:
  path: /index
  defaults: &blog_redirect
    _controller: FrameworkBundle:Redirect:redirect
    route: blog
    permanent: true

blog_page:
  path: /blog
  defaults: *blog_redirect
