Frame Relay, birden fazla kullanıcının haberleşme kaynaklarını paylaşması esasına dayanır ve ağa bağlanan tek fiziksel hat aracılığıyla birden fazla nokta ile görüşmelerine olanak tanır. Bu noktada artık iki uç arasında sürekli ayrılmış band genişliği yerine gereksinim duyuldukça kısa zaman aralıklarında kullanılan daha yüksek band genişlikleri söz konusudur. Merkez-şube bağlantılarında bir fiziksel hat üzerinden birden fazla nokta ile bağlantı yapılması sayesinde, Frame Relay, kiralık devrelerle karşılaştırıldığında, gereksinim duyulan devre sayısının azalması ile uygun maliyetli bir alternatif olarak kullanılmaktadır.

2. Frame-Relay Map’in oluşturulması
Cihazlara ip addressleri verelim.IP adresi yapılandırmasının, yanı sıra tüm IP DLCI eşlemeleri için fiziksel bir seri interface altında yapılmalıdır. Çok noktaya yayın veya yayın paketlerini bu interfacelerde istiyorsak, DLCI broadcast yayın seçeneği eklenmelidir.
